A tennis ball of mass m = 0.050 kg and speed v = 45 m/s strikes a wall at a 45° angle and rebounds with the same speed at 45° (What is the impulse given the wall? Magnitude
ok demon figure it out man! ^^ i bet she'll thank u a lot

Magnitude of the impulse is I = 2mvcosθ = 2(0.050kg)(45m/s)cos45o = 3.18 kg.m/s
