Jeremy kicks a soccer ball with a force of 250N. Jeremy got a running start and was 2m away from the ball before he made contact, The ball traveled 25m and hit a mailbox with a force of 200N. The mailbox does not move at all, but the ball rolls backwards 3m in the direction of Jeremy. What was the work done by Jeremy to the soccer ball?
To find the work done by Jeremy on the soccer ball, we need to calculate the kinetic energy of the ball before and after it hits the mailbox.
First, let's calculate the initial kinetic energy of the ball:
Initial velocity of the ball, v0 = 0 (initially at rest)
Initial kinetic energy = 0
Next, let's calculate the final kinetic energy of the ball after it has traveled and hit the mailbox:
Final velocity of the ball, vf = 0 (the ball stops after hitting the mailbox)
Final kinetic energy = 0
The work done by Jeremy on the soccer ball can be calculated using the work-energy principle:
Work done = change in kinetic energy
Work done = Final kinetic energy - Initial kinetic energy
Work done = 0 - 0
Work done = 0
Therefore, the work done by Jeremy on the soccer ball is 0.
