I'm struggling to do this problem.
"When Babe Ruth hit a homer over the 7.0m -high right-field fence 120m from home plate, roughly what was the minimum speed of the ball when it left the bat? Assume the ball was hit 1.0m above the ground and its path initially made a 30∘ angle with the ground."
My work:
Since initial Y is not 0, the range equation cannot be used.
initial Y: 1m
final Y: 7m
initial Y velocity: ?
final Y velocity: ?
a = -9.8m/s
t = ? (but is same as T for X)
initial X: 0m
final X: 120m
initial X velocity: ?
final Y velocity: ?
a = 0
t = ? (but is same as T for Y)
I have attempted manipulating the 3 main kinematic equations to try to set T equal to each other for each component but I am empty handed.
Can someone help me step on the right foot?
Also, if I am struggling with this problem, is it still possible for me to obtain a PhD in physics one day?
