A spinning ball of mass 0.3 kg hits the floor with a speed of 6 m/s with the angle 0 = 30°. What are the x and y components of the momentum just before the ball hits the floor? Px 0.9 kg m/s %3D Py -1.56 kg m/s %3D L. +y +x The net impulse delivered to the ball during this bounce is (-0.32 i+ 2.8 j) N s. What is the speed of the ball immediately after the bounce? Answer in m/s. Hint: the momentum impulse relation is a vector relation -- even though the question asks for speed you will need to find either the momentum vector or the velocity vector after the collision fırst before you can find the speed. What is the average normal force that the floor exerts on the ball during the collision if the ball is in contact with the ground for 0.382 seconds? Answer in terms of newtons. Hint: you need to take into account that y component of the net impulse is due to both the normal force and gravity. You can check your answer by repeating the question using Newton's 2nd law. >

A block of mass m1 = 2 kg and speed v1 = 0.40 m/s collides with a block of mass m2 = 5 kg that is initially at rest. If the two blocks stick together, what is their speed right after the collision?
Mass A is initially moving with a velocity of 12 m/s in the +x-direction. Mass B is twice as massive as mass A and is initially at rest. After the two objects collide, the two masses move together as one with a velocity of 4 m/s in the +x-direction. Is momentum conserved in this collision?
Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of mA = 16.1 kg and an initial velocity of ν¯0A = 8.59 m/s, due east. Object B, however, has a mass of mB = 29.9 kg and an initial velocity of ν¯0B = 5.68 m/s, due north.
