Suppose you throw a ball with mass 0.40 kg against a brick wall(Figure 1). It hits the wall moving horizontally to the left at 30 m/sand rebounds horizontally to the right at 20 m/s. Find the impulse ofthe force exerted on the ball by the wall. If the ball is in contact withthe wall for 0.010 s, find the average force on the ball during theimpact. Suppose, rather than throwing a ball, you throw a lump of clay with mass 0.75 kg andinitial velocity 33 m/s. When it hits the wall, the lump of clay sticks to the wall. Find theaverage force exerted on the wall by the lump of clay if it comes to a stop in 0.010 s.Express your answer with the appropriate units.F3=ValueUnirs
