A woodblock of mass Mw = 200 g is projected from the ground at a speed v0 = 35 m/s and at an angle, θ0 = 50º. When at height h = 24 m the woodblock was hit by a bullet of mass Mb = 25 g which was moving at vb = 220 m/s and at an angle θb = 70º. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground. Then they move on the ground that has a coefficient of kinetic friction µk = 0.5 and starts to compress a horizontal spring at point B.

Shown is a collision between two pucks on an air hockey table. Puck a has mass 0.025kg and is moving along the x-axis with a velocity of +5.5m/s. It makes a collision with puck B, which has a mass of 0.05kg and is initially at rest. The collision is not head-on. After the collision the pucks fly off with the angles as shown. +5.5 m/s At rest Before collision 65 37- After collision What is the speed of puck A? (4) m/s What is the speed of puck B? (4) m/s
