Two average forces. A steady stream of 0.250 kg snowballs is shot perpendicularly into a wall at a speed of 4.00 m/s. Each ball sticks to the wall. the magnitude F of the force on the wall as a function of time t for two of the snowball impacts. Impacts occur with a repetition time interval tr  50.0 ms, last a duration time interval td  10 ms, and produce isosceles triangles on the graph, with each impact reaching a force maximum Fmax  200 N. During each impact, what are the magnitudes of (a) the impulse and (b) the average force on the wall? (c) During a time interval of many impacts, what is the magnitude of the average force on the wall?
