A block of mass

m

is lowered with the help of a rope of negligible mass through a distance ‘

d

’ with an acceleration of

\frac{g}{3}

. Work done by the rope on the block is

View answer and explanation

Correct option: B

\frac{{ - 2Mgd}}{3}

Option B (

\frac{{ - 2Mgd}}{3}

) is correct because the work done by the rope is negative as it acts upwards while the block moves downwards, and the tension is less than the weight due to the downward acceleration.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in

\mathrm{m}{\mathrm{s}^{ - 1}}

is A force

\mathrm{\vec F} = - K\left( {y\hat i + x\hat j} \right)

(where K is a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x-axis to the point (a,0) and then parallel to the y-axis to the (a,a). The total work done by the force

\mathrm{\vec F}

on the particle is A motor is used to deliver water at a certain rate from a given pipe. To obtain 3 times water from same pipe in same time, by what factor should power of the motor be increased.
