Homework Statement
A baseball player throws a ball at an initial velocity of 27m/s. It lands 140m away at 6.4 seconds.
(A) what is the angle he threw it at?
(B) what is the maximum height?
Homework Equations
The Attempt at a Solution
I found the angle to be 36 degrees using the formula d=ViΔt+1/2aΔt^2
140 = 27cosθ(6.4)
140/6.4 = 27cosθ
θ=36 degreesHowever when I went to calculate the maximum height I I subbed it into my formula:
dxmax= 27sin36•3.2+1/2(-9.81)•3.2^2
dxmax=0.5574m
Which I find quite unreasonable?
