A ball of mass m = 1.80 kg is released from rest at a heighth = 65.0 cm above a light vertical spring of force constantk as in Figure P5.64a. The ball strikes the top of the springand compresses it a distance d = 9.00 cm as in Figure P5.64b.Neglecting any energylosses during the colli-sion, find (a) the speedof the ball just as ittouches the spring and(b) the force constant ofтthe spring.ьFigure P5.64

A block of mass 0.500 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x (Fig. P7.79). The force constant of the spring is 450 N/m. When it is released, the block travels along a frictionless, horizontal surface to point , the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The blocks speed at the bottom of the track is = 12.0 m/s, and the block experiences an average friction force of 7.00 N while sliding up the track. (a) What is x? (b) If the block were to reach the top of the track, what would be its speed at that point? (c) Does the block actually reach the top of the track, or does it fall off before reaching the top?
