A ball of mass m = 1.75 kg is released from rest at a height h = 58.0 cm above a light vertical spring of force constant k as in Figure [a] shown below. The ball strikes the top of the spring and compresses it a distance d = 7.90 cm as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following. I h m k T www a b (a) Find the speed of the ball just as it touches the spring. 3.37 m/s (b) Find the force constant of the spring. 3.19 Your response differs from the correct answer by more than 10%. Double check your calculations. kN/m
