Speed =143 km/hr;
Distance=66 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=66/39.72
Force=1.67N
