Answer:
The ballplayer put 6560 newtons of force onto the ball.
Step-by-step explanation:
List out all the information the question provides:
Ball mass: 0.16
Initial Velocity: 38 m/s
Final velocity: -44 m’s (Remember the negative sign!! The ball is going the OPPOSITE direction.)
Time: 0.002
Change in velocity: 82 (difference of 38 and -44)
This is the formula:
F∆t=m∆v
(∆t= time, m is mass, ∆v is the change in velocity.)
then solve.
F•(0.002)=(0.16•82)
F•(0.002)=(13.12)
divide 13.12 by ∆t
F=6560
The ballplayer put 6560 newtons of force onto the ball.
Hope this helps! It's pretty straightforward once you get the hang of it.
