Block $A$ of weight $100\mathrm{ }\mathrm{N}$ rests on a frictionless inclined plane of slope angle $30°$ as shown in the figure. A flexible cord attached to $A$ passes over a frictionless pulley and is connected to block $B$ of weight $W$. Find the weight $W$ for which the system is in equilibrium.

A bullet of mass $40 \mathrm{g}$ moving with a speed of $90\mathrm{ }\mathrm{m}\mathrm{ }{\mathrm{s}}^{-1}$ enters heavy wooden block and is stopped after a distance of $60 \mathrm{cm}$. The average resistive force exerted by the block on the bullet is

A constant force acting on a body of mass of $5 \mathrm{kg}$ changes its speed from $5 \mathrm{m}\mathrm{ }{\mathrm{s}}^{-1} \text{to} 10\mathrm{ }\mathrm{m}\mathrm{ }{\mathrm{s}}^{-1}$ in $10 \mathrm{s}$ without changing the direction of motion. The force acting on the body is
