A ball of mass 0.45 kg which is initially at rest is hit by a bat. The bat remains in contact with the ball for 3 × 10^{-3} s. During this time period the force on the ball by the bat is given as F (t) = [(\alpha\times10^6)t-(\beta\times10^9)t^2]N where α and β are constants. The ball’s speed.immediately as it loses contact with the bat is 20 m/s. The collect relation between or α and β is

Correct Answer is : α - 2β = 2

A ball of mass 0.45 kg which is initially at rest is hit by a bat. The bat remains in contact with the ball for 3 × 10−3 s. During this time period the force on the ball by the bat is given as F (t) = [(α×106)t−(β×109)t2]N where α and β are constants. The ball’s speed.immediately as it loses contact with the bat is 20 m/s. The collect relation between or α and β is

α - 2β = 2
2α + β = 1
α - β = 2
2α - β = 2
