.125*25=total mass*combined velocity
=M+.125)V
The time to fall off the head is
1.85=9.8t^2/2
solve for time,t
then
V*t=8.5 solve for V
Put that back into the first equation, solve for M
William Tell shoots an apple from his son's head.The speed of the 125-g arrow just before it strikes the apple is 25.0m/s, and the time of impact it is travelling horizontally.If the arrow strikes in the apple and the Arrow/Apple combination strikes 8.50m behind the son's feet, how massive was the apple?
