Homework Statement
The fastball of a famous pitcher in the National League has
been clocked in excess of 95 mph. Calculate the work done
by the pitcher in accelerating the ball to that speed. The
mass of a baseball is 0.145 kg.
mass = 0.145 kg
final velocity (in m/s) = 42.4688 m/s
initial velocity = 0 m/s
Homework Equations
F = ma
w = F*distance
The Attempt at a Solution
I tried setting up F = ma to find something, but the only known variable is mass. I also tried kinematics, but there are only two known variables that go into the equations and I can't isolate any variables. Is there an equation I'm forgetting, or am I just looking at this problem the wrong way? Thanks.
