Question

A tennis ball covers a distance of 12 meters in 0.4 seconds what is the velocity of the tennis ball?

Answer 1

V=d/t
V=12/0.4
V=30 m/s

Answer 2

Answer:

30m/s

Explanation:

Given parameters:

Distance  = 12m

Time taken  = 0.4s

Unknown:

Velocity of the tennis ball = ?

Solution:

Velocity of a body is the displacement per unit of time.

  Velocity  = $\frac{displacement}{time}$  

So;

      Velocity  = $\frac{12}{0.4}$   = 30m/s
