Question

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. Calculate its average acceleration.

Answer 1

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 :

`a = \frac{\text{Change in speed}}{\text{Time taken }}\\\\a = (10-30)/(0.5 )\ m/s^2\\\\a = -40\ m/s^2`

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