Question

Why does a cricket ball fly off after being hit by a cricket ball?

Answer 1

since it depends on which part of the bat is moving at 60 km/hr and it depends on where the ball makes contact with the bat. Suppose that the ball strikes the middle of the bat rather than near an edge and suppose that 60 km/hr is the speed of the impact point on the bat rather than the speed of the tip or the handle. We also need to know the mass of the bat, or better still we need to know how fast the ball comes off the bat when the bat is not swung at all. Suppose that the bat is used just to block the ball and the ball bounces off the bat at 20 km/hr. If E = ratio of bounce speed to incident speed = 20/100 = 0.2 then the speed of the ball when the bat is swung at speed V is 20 + (1 + E)V = 20 + 1.2 x 60 = 20 + 72 = 92 km/hr. For most bats, E varies from about 0.1 near the tip to about 0.3 half way up the bat. E is smallest near the tip of the bat but V is biggest there when the batter takes a huge swing at the ball.

Answer 2

When the ball was hit by a batsman the ball fly off because the batsman creates a force opposite to the gravitational force and more than the gravitational force of the earth and hence the ball gets the less gravitational force and experirnce more normal force
