Question 99

A bowler throws a cricket ball at a speed of 120 km/h. How long does this ball take to travel a distance of 20 m to each the batsman?

Answer 1

The speed of the cricket ball

$=120km/h$

$=\frac{120\times 1000}{60}=2\times 1000=2000m/min$

$Nowspeedinm/s=\frac{2000}{60}=\frac{200}{6}=\frac{100}{3}m/s$

So, 20 m can be covered in
$\frac{20\times 3}{100}=\frac{60}{100}=0.6s$
