When the force that causes the deformation disappears, the spring comes back to its initial shape, provided the elastic limit was not exceeded. Hooke's law states that for an elastic spring, the force and displacement are proportional to each other. It means that as the spring force increases, the displacement increases, too.

9. An object undergoes SHM and position as a function of time is presented by the following formula: x= (0.5 m) Cos (πt). What is the amplitude of oscillations? A) 2 m B) 1 m C) 0.5 m D) 0.1 m 10. The position as a function of time of a mass-spring oscillating system is presented by the graph.

B) The frictional force and force exerted by the spring scale on the block, because they are a Newton’s third-law pair. C) The normal force and the frictional force exerted on the block, because objects always exert forces of equal magnitude on each other.

50. A 250g block is dropped onto a relaxed vertical spring that has a spring constant of k=2.5N/cm. The block becomes attached to the spring and compresses the spring 12 cm before momentarily stopping. While the spring is being compressed, what work is done on the block by (a) the gravitational force on it and (b) the spring force?

A particle of mass m is moving with a constant speed v in a circular path in a smooth horizontal plane (plane of paper) by a spring force as shown in Fig. If the natural length of the spring is l 0 and stiffness of the spring is k, find the elongation of the spring.

(e) none of the above Multiple Choice Question 2 Two 1.0 Kg point masses a distance D apart each exert a gravitational force of magnitude F on the other one. If 1.0 Kg is now added to each mass, the gravitational attraction exerted by each would be (a) F (b) 2F (c) 3F (d) 4F Multiple Choice Question 3 An object weighs 200 N on the earth’s ...

block is a spring in its equilibrium position with spring constant k=2 N/m. The spring has a massless platform that is attached to its top (the top of the spring with platform is even with the ground level). The block lands on and compresses the spring by a distance x. This is not a homework problem - feel free to round your answers as you go.

14 A 5-newton force causes a spring to stretch 0.2 meter. What is the potential energy stored in the stretched spring? (1) 1 J (3) 0.2 J (2) 0.5 J (4) 0.1 J 15 A 40.-kilogram student runs up a staircase to a floor that is 5.0 meters higher than her starting point in 7.0 seconds. The student’s power output is (1) 29 W (3) 1.4 × 103 W

The edge of the table is a height h above the top of the box The spring has a spring constant k . By what distance x should the child compress the spring so that the marble lands in the center of the box? The sacrum axis of the. vertebral column. Assume that mass of the head and arms is m2 =.

Question 145506: Problem: Hooke’s Law states that the distance, d, a string is stretched varies directly with the force, F, applied to the spring. If a force of 12 pounds stretches a spring 3 inches, how far will the spring stretch when a force of 30 pounds is applied? Answer by [email protected](22270) (Show Source):

SOLUTION: The length a spring stretches is directly proportional to the force applied. If a force of 6 pounds stretches a spring 4 inches, how much force is necessary to stretch the same spr Algebra -> Human-and-algebraic-language -> SOLUTION: The length a spring stretches is directly proportional to the force applied.

A force acting upon an object for some duration of time results in an impulse. The quantity impulse is calculated by multiplying force and time. Impulses cause objects to change their momentum. And finally, the impulse an object experiences is equal to the momentum change that results from it.

On point A, the centripetal force is the sum of gravity force and the normal force: N + mg. = mv2. Two objects are connected by a light string passing over a light, fric-tionless pulley as shown in the gure The object of mass m1 = 6.60 kg is released from rest at a height h = 3.40 m above the table.

The weight and the normal force are both in the vertical direction; if there is no friction a force F would be the only force with a horizontal component, and thus it will always produce an acceleration. 16. A ball with a weight of 1.5 N is thrown at an angle of 30 above the horizontal with an initial speed of 12 m/s.

(b) A mass is attached to the spring and a new equilibrium position is reached ([latex] {y}_{1}={y}_{o}-\text{Δ}y [/latex]) when the force provided by the spring equals the weight of the mass. (c) The free-body diagram of the mass shows the two forces acting on the mass: the weight and the force of the spring.

A spring with a 4 kg mass has natural length 1 m and is maintained stretched to a length of 1.3 m by a force of 24.3 N. If the spring is compressed to a length of 0.8 m and then released with zero velocity, find the position of the mass at any time t. Here is my work so far: 24.3/0.3 = k*0.3/0.3 k = 81 m*k" + k*x = 0 4*k" + 81*x = 0 x = +/- 4.5i
