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

Which one of the following statement is false?

Q3PhysicsUnit 4: Work, Energy and Power

A body of mass 5 kg has momentum of

10 \mathrm{kg} \mathrm{m} / \mathrm{sec} .

When a force of

0.2 \mathrm{N}

is applied on it for 10 sec, the change in its kinetic energy is:

Q4PhysicsUnit 4: Work, Energy and Power

The graph between the resistive force acting on a body and the position of the body travelling in a straight line is shown in the figure. The mass of the body is

25 \mathrm{kg}

and initial velocity is 2 m/s.When the distance covered by the bodyi

s 4 \mathrm{m},

its kinetic energy would be

Q5PhysicsUnit 4: Work, Energy and Power

\mathbf{A}

3 k g

object has initial velocity

(6 \hat{i}-

\mathbf{2} \hat{\boldsymbol{j}}) \boldsymbol{m} / \boldsymbol{s} .

The total work done on the object if its velocity changes to

(8 \hat{i}+

4 \hat{j}) m / s

is :

Q6PhysicsUnit 4: Work, Energy and Power
