Given :

A badminton shuttlecock leaves the racquet traveling 30 m/s.

It goes over the net 0.5  seconds later with a speed of 10 m/s.

To Find :

The average acceleration of the shuttlecock.

Solution :

We know, average acceleration(a) is given by :

Therefore, the average acceleration is -40 m/s².

pretty sure it's false
