Hey all, I'm don't have the firmest grasp on physics and a little help would be much appreciated!
So two questions:
1)a physics student watching a tennis match states, "while the ball is in contact with the racquet, the racquet exerts a larger force on the ball than the ball does on the racquet because the racquet has to stop the ball and then reverse its motion"
What if anything is wrong with this statement?
2) a student observes a rubber ball hitting a wall and rebounding states, "The wall exerts a larger force on the ball than the ball exerts on the wall, because the ball undergoes an acceleration but the wall doesn't move. That is, the ball goes from an initial speed to zero, and then from zero to the rebound speed but the wall does not accelerate since it is stationary the whole time".
What if anything is wrong with this statement?
Thanks in advance!
