Question
During a neighborhood baseball game in a vacant lot, a particularly wild hit sends a 0.148 kg baseball crashing through the pane of a second-floor window in a nearby building. The ball strikes the glass at 15.5 m/s , shatters the glass as it passes through, and leaves the window at 10.1 m/s with no change of direction. What is the direction of the impulse that the glass imparts to the baseball

Answer:
Explanation:
mass of baseball, m = 0.148 kg
initial velocity, u = 15.5 m/s
final velocity, v = 10.1 m/s
Impulse is defined as the change in momentum of the body.
Impulse = change in momentum
I = m (v – u)
I = 0.148 (10.1 – 15.5)
I = – 0.8 Ns
