Answer:
The work done is 13.875 J.
Explanation:
Given that,
Mass of ball = 0.25 kg
Initial speed = 20 m/s
Final speed = 17 m/s
We need to calculate the work done
Using formula of work done
Work done by the friction
Negative sign shows the friction always against displacement.
Hence, The work done is 13.875 J.
