Homework Statement
A bat strikes a 0.145 kg baseball. Just before impact, the ball is traveling horizontally to the right at 50.0 m/s, and it leaves the bat traveling to the left at an angle of 35 degrees above horizontal with a speed of 60.0 m/s. The ball and bat are in contact for 1.65 milliseconds.
A) Find the horizontal component of the average force on the ball. Take the x-direction to be positive to the right
B) Find the vertical component of the average force on the ball.
Express answers with two significant figures.
Homework Equations
F= ma
V= Vo + at
The Attempt at a Solution
First I plugged into the kinematics equation:
60 m/s= 50 m/s + a (0.00165 s)
a= 6060.61 m/s^2
Then I simply used sin and cos to get the components:
6060.61sin(35) = 3476.2 = 3500 (sig figs) = Fy
6060.61cos(35) = 4694.56 = 4700 (sig figs) = Fx
Both of these are wrong. What am I doing wrong?
