The particle of mass $50\, kg$ is at rest. The work done to accelerates it by $20\,m/s$ in $10\,s$ is

The earth circles around the sun once a year. The work which would have to be done on the earth to bring it to rest relative to the sun is, (Ignore the rotation of earth about its own axis) given that the mass of the earth $=6 \times 10^{24}\, kg$ and distance between sun and earth is $1.5 \times 10^{8}\, km$)

A $60\, kg$ weight is dragged on a horizontal surface by a rope through a distance of $2m$. If coefficient of friction is $ \mu =0.5, $ the angle of rope with surface is $60^{\circ}$ and $g=9.8\,m/{s}^{2}, $ then work done is

A cord is used to lower vertically a block of mass $M$ by a distance $d$ with constant downward acceleration $\frac{g}{4}$. Work done by the cord on the block is

A spring $40 \,mm$ long is stretched by the application of a force. If $10 \,N$ force required to stretch the spring through $1 \,mm$, then work done in stretching the spring through $40\, mm$, is
