Q1PhysicsUnit 4: Work, Energy and Power

A cricket ball of mass

150 g

moving with a speed of

126 k m / h

hits at the middle of the bat, held firmly at its position by the batsman. The ball moves straight back to the bowler after hitting the bat. Assuming that collision between ball and bat is completely elastic and the two remain in constant for

0.001 s,

the force that the batsman had to apply to hold the bat firmly at its place would be:

Q2PhysicsUnit 4: Work, Energy and Power

Assertion (A) : The value of coefficient of restitution is independent of the masses and velocities of the colliding bodies but depends on their materials. Reason (R) : Coefficient of restitution is the ratio of the relative velocity of separation or the relative velocity of approach

Q3PhysicsUnit 4: Work, Energy and Power

Water jet is coming out of a hose pipe of diameter

20 \mathrm{cm}

with speed

20 \mathrm{cm} / \mathrm{sec}

It strike a man inelastically. Find the force exerted by water jet on the person.

Q4PhysicsUnit 4: Work, Energy and Power

A plastic ball falls from a height of 4.9 metre and rebounds several times from the floor. What is the coefficient of restitution during the impact with the floor if 1.3 seconds pass from the first impact to the second one?

Q5PhysicsUnit 4: Work, Energy and Power

A ball rebounds after colliding with the floor, then in case of inelastic collision:

Q6PhysicsUnit 4: Work, Energy and Power

A metal ball of mass

2 k g

moving with velocity of

36 k m / h

has a head on collision with a stationary ball of mass 3kg. If after the collision the two balls moves together, the loss in kinetic energy due to collision is (in J)

Q7PhysicsUnit 4: Work, Energy and Power

Ball A strikes with velocity u elastically with identical ball

B

at rest, inclined at an angle of with line joining the centers of two balls. What will be the speed of ball B after the collision:

Q8PhysicsUnit 4: Work, Energy and Power
