Question

If a bowler throws a ball at speed of 143 km/hr. And the ground is 63m long. By what force the batsman should hit for a sixer?​

Answer 1

Answer:

The force applied is 1.58 N

Step-by-step explanation:

Speed =143 km/hr;

Distance=63 m;

As given the speed value in km/hr, we need to convert it into m/sec,

km/hr to m/sec=1000/3600;

Substitute the above value in to the speed value which is 143km/hr,

Therefore 143 km/hr to m/sec

=>143 x 1000/3600

Simplification of 1000/3600 is 5/18, substitute this in the above

=>143 x 5/18

After multiplying we get the value in m/sec which is 39.72,

=>39.72 m/sec

From the question, we need to find how much force should be applied from the batsman to hit a six,

Force=63/39.72

Force=1.58N
