1. Question
A 0.145kg baseball moving horizontally at 35.0m/s strikes a bat and is popped straight up to a height of 55.6m before turning around. If the contact time is 0.50ms, calculate the average force on the ball during the contact.
p=mv
Δp=mΔv=fΔt
Ek=0.5mv^2 (?)
Ep=mgh (?)
pinitial=(35)(.145)=5.075 kg*m/s
I was going to use the time that was given, but I'm unsure if the "ms" unit was a typo or was written on purpose. If it was on purpose, I'm unsure how I should use it
