1. A baseball of mass 0.1 kg is moving horizontally at a speed of 40 m/s when it is stuck by a bat. It leaves the bat in a direction at an angle φ = 30◦ above its incident path and with a speed of 50 m/s.
• Find the impulse the bat exerts on the ball.
• Assuming the collision lasts for 0.0015 s, what is the average
force the bat is exerting on the ball during the impact?
2. F=m(v-u)/t and I=f x change in temperature
3. My attempt was: I subbed the figures into the force equation like so f=0.1(50-40)/0.0015=666.6
I know this is incorrect because I don't know what to do with the angle that was given in the question.
