An impulse of 100 N.s is applied to a 20.0 kg mass traveling at a speed of 50 m/s. Determine the speed of the mass after the impulse was applied. [Show all work including the equation and the substitution with units.]
Impulse = change in momentum
100 N = m * change in v
100N = 20 kg * change in v
5 m/s = change in velocity
if the impulse is applied in line with the direction of travel, the object will now be travelling 55 m/s
if the impulse is applied OPPOSITE to the direction of travel , the object is now traveling 45 m/s
