A baseball with a mass of 0.145 kilograms collides with a bat at a velocity of 44 meters/second. The ball bounces off the bat with a speed of 49 meters/second in the opposite direction. What is the impulse?A baseball with a mass of 0.145 kilograms collides with a bat at a velocity of 44 meters/second.

Momentum= FΔt=mΔv=Δp 

Assuming that the initial direction of the ball is negative; 

(0.145)(49-(-44)) <-- Δv= final velocity-initial 
(0.145)(49+44)
= 13.485 Ns impulse in the opposite direction 

Hope I helped :)
