Given :
The average acceleration of a tennis ball that has an initial velocity of 6.0 m/s.
and a final velocity of 7.3 m/s.
It is in contact with a tennis racket for 0.094 s
To Find :
The average acceleration of the tennis ball.
Solution :
We know, average acceleration is given by :
Therefore, average velocity is given by 13.83 m/s².
Hence, this is the required solution.
Considering that the book is moving with constant speed, the force applied by Anna must be the same that the friction force:
If we clear the previous equation:
If we clear the previous equation:
