The figure below shows a stationary block of mass 1 kg resting on a frictionless surface and attached to one end of a spring with spring constant 900 N/m. The spring is initially at its relaxed length and is connected to a rigid wall. A bullet of mass 5 g moving with speed 400 m/s is fired into the block and emerges from the other end of the block. The collision is not elastic. If the block moves a distance of 5 cm to the right after impact, find the speed v of the bullet after the collision and before it hits the wall. Assume that the block doesn't start moving until the bullet completely emerges from the block. (Hint: conserve momentum during the collision, conserve energy after the collision.) 400 m/s www 5 cm www

Two skateboarders, with masses m1 = 75.0 kg and m2 = 65.0 kg, simultaneously leave the opposite sides of a frictionless half-pipe at height h = 4.00 m as shown in Figure P11.49. Assume the skateboarders undergo a completely elastic head-on collision on the horizontal segment of the half-pipe. Treating the skateboarders as particles and assuming they dont fall off their skateboards, what is the height reached by each skateboarder after the collision? FIGURE P11.49
A 9.50-g bullet, moving horizontally withan initial speed v0, embeds itself in a 1.45-kg pendulum bob that isinitially at rest. The length of the pendulum is L = 0.745 m. Afterthe collision, the pendulum swings to one side and comes to restwhen it has gained a vertical height of 12.4 cm. (a) Is the kineticenergy of the bullet–bob system immediately after the collisiongreater than, less than, or the same as the kinetic energy of thesystem just before the collision? Explain. (b) Find the initial speedof the bullet. (c) How much time does it take for the bullet–bobsystem to come to rest for the first time?
Two solid iron spheres of masses m and 2m respectively, are suspended from two inextensible ropes of length l. We separate the ball of mass m from its equilibrium position at an angle α, keeping the string extended in the same plane. The mass is released and collides elastically with the sphere of mass 2m. The speed of the sphere sphere of mass m immediately after the collision is:
A ball with mass m travels with speed v perpendicular to a uniform stick with mass m and length l, which is initially lying at rest on a frictionless table. where along the stick shoudl the ball collide elastically with it, so that the ball and the center of the stick move with equal velocities after the collision?
