Question

Two blocks are sliding across a horizontal frictionless tabletop. Block A has a mass

of 5 kg, and it is sliding directly southward with a speed of 8 m/s. Block B has a

mass of 7 kg, and it is sliding directly westward with a speed of 4 m/s. The blocks

then collide and stick together. What is the speed of the new combined block after

the collision?

a) 2 m/s

b) 4 m/s

c) 6 m/s

d) 8 m/s

Two boxes are sliding to the right on a horizontal frictionless surface. Box 1 is trailing box 2. Box 1 has a mass of 2 kg and a speed of 5 m/s, while box 2 has a mass of 4 kg and a speed of 3 m/s. Eventually, box 1 catches up to box 2 and experiences a completely inelastic collision with box 2. What is the speed of the two blocks after the collision?

A block of mass m = 8.40 kg, moving on a horizontal frictionless surface with a speed 4.20 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 8.40 kg block recoils with a speed of 0.400 m/s. In the figure, the blocks are in contact for 0.200 s. What is the magnitude of the average force on the 8.40 kg block, while the two blocks are in contact?
