A4 kg billiard ball moving on a horizontal surface has a speed of 16 m/s when it strikes a horizontal coiled spring is brought to rest in a distance of 0.75 m. what is the spring constant of the spring?

1820.44 N/m

Explanation:

mass of ball, m = 4 kg

velocity of ball, v = 16 m/s

distance x = 0.75 m

let k be the spring constant.

By the use of conservation of energy,

the kinetic energy of the ball is equal to the potential energy of the spring

4 x 16 x 16 = K x 0.75 x 0.75

K = 1820.44 N/m

Thus, the spring constant is 1820.44 N/m.

i think the answer would be reserve.
