Question

a bowler throws a cricket ball at a speed of 120 km per hour how long does this ball take to travel a distance of 20 m to reach the batsman

Answer 1

The ball takes 0.6s to reach the batsman.

Given:

Speed of the ball= 120km/h

Distance between batsman and bowler= 20m

To find:

Time taken by ball to reach the batsman.

Solution:

We know Speed= Distance/Time

given speed is in km/h form, converting it to m/s form

We know 1km=1000m , 1h=3600s

1km/h=1000/3600m/s=5/18m/s

120km/h=120*5/18=100/3m/s

Now using formula,

100/3= 20/T

T=20*3/100

T=3/5s=0.6s

Therefore, the ball takes 0.6s to reach the batsman.
