A 0.0200-kg bullet is shot horizontally and collides with a 3.65-kg block of wood. The bullet embeds in the block, and the block slides along a horizontal surface for 2.30 m. If the coefficient of kinetic friction between the block and surface is 0.400, what was the original speed of the bullet? m/s

A boy of mass 40.0 kg is sledding down a 70.0-m slope starting from rest. The slope is angled at 15.0° below the horizontal. After going 12.0 m along the slope, he passes his friend, who hops onto the sled. The friend has a mass of 50.0 kg, and the coefficient of kinetic friction between the sled and the snow is 0.120. Ignoring the mass of the sled, find their speed at the bottom. m/s
