A force of $10 \mathrm{kgf}$is applied on a body of mass $100 \mathrm{g}$ initially at rest for$0.1\mathrm{s}$. Calculate the momentum acquired by the body.

A force of$10 \mathrm{kgf}$is applied on a body of mass $100 \mathrm{g}$initially at rest for$0.1\mathrm{s}$. Calculate the distance travelled by the body in $0.1\mathrm{s}.$ Take $\mathrm{g} = 10 \mathrm{N} {\mathrm{kg}}^{-1}$

A body of mass $50 \mathrm{g}$is moving with a velocity of $10 {\mathrm{ms}}^{-1}$. It is brought to rest by a resistive force of $10 \mathrm{N}$. Find the distance that the body will travel after the resistance force is applied.

A toy car of mass $500 \mathrm{g}$ travels with a uniform velocity of $25 \mathrm{m} {\mathrm{s}}^{-1}$ for $5 \mathrm{s}$. The brakes are then applied and the car is uniformly retarded and comes to rest in further $10 \mathrm{s}$. Calculate the retardation.

A uniform car of mass $500 \mathrm{g}$ travels with a uniform velocity of $25 \mathrm{m} {\mathrm{s}}^{-1}$ for $5 \mathrm{s}$. The brakes are then applied and the car is uniformly retarded and comes to rest in further $10 \mathrm{s}$. Calculate the distance which the car travels after the brakes are applied.

A toy car of mass$500 \mathrm{g}$ travels with a uniform velocity of $25 \mathrm{m} {\mathrm{s}}^{-1}$ for $5 \mathrm{s}.$ The brakes are then applied and the car is uniformly retarded and comes to rest in further $10 \mathrm{s}$. Calculate the force exerted by the brakes.

A truck of given mass $5 \times {10}^3 \mathrm{kg}$ starting from rest travels a distance of$0.5 \mathrm{km}$ in $10 \mathrm{s}$ when a force is applied on it. Calculate the acceleration acquired by the truck.

A truck of mass $5 \times {10}^3 \mathrm{kg}$ starting from rest travels a distance of $0.5 \mathrm{km}$ in $10 \mathrm{s}$ when a force is applied on it. Calculate the force applied.
