Homework Statement
Baseball is hit at 60.0m/s at an angle of 30 degrees to the horizontal. Assuming the field is level find:
Time ball was in air
How long it was in the air
How far did it go
Given
Assume up is +ve
Calculated data within brackets
Horizontal
v=(52m/s)
d=
t=
Vertical
vi=(30m/s)
vf=
a=-9.8m/s
d=
t=
Ball
v=60.0m/s[Forward30Up]
Homework Equations
sinθ=opp/hyp
cosθ=adj/hyp
d=ut+0.5at^2
v=d/t
The Attempt at a Solution
Assume (variable)(h) means a horizontal variable and (variable)(v) means the vertical variable.
So i drew out the vector diagram for the ball, with v(ball)=v(h)+v(v), knowing angle is 30
Using sine and cosine i was able to determine the values for v(h)=52m/s and v(v)=30m/s.
(Calculated info written in the givens within brackets)
So now I am stuck...I am not given enough information to determine any other variables, I think?
