The elastic potential energy of a spring

(A): The elastic potential energy of spring increases when it is elongated and decreases when it is compressed. (R) : Work done on a spring is independent of the force constant of the spring.

A spring is compressed by a toy cart of mass 150g. On releasing the cart, it moves with a speed of 0.2 m//s . Calculate the elastic potential energy of the spring.

(a) What is elastic potential energy of a spring ? Obtain the relation for elastic P.E. U=(1)/(2)kx^(2) . Where k is force constant of spring, x is extension or compression produced in the spring.

A 242 × 10^(4)kg freight car moving along a horizontal rail road spur track at 7.2 km/hour strikes a bumper whose coil springs experiences a maximum compression of 30 cm in stopping the car. The elastic potential energy of the springs at the instant when they are compressed 15 cm is

A 5.0g marble is fired vertically upward using a spring gun. The spring must be compressed 8.0 cm if the marble is to just reach a target 20 m above the marble's position on the compressed spring. (a) What is the change DeltaU_(g) in the gravitational potential energy of the marble-Earth system during the 20 m ascent ? (b) What is the change DeltaU_(s) in the elastic potential energy of the spring during its launch of the marble ? (c) What is the spring constant of the spring ?
