Question

If a car and truck are moving with same momentum , the velocity of car is ________________ than the velocity of truck.

Answer 1

Explanation:

1. Momentum(p) is the product of the mass(m) of an object and the velocity(v) of its motion.$(\mathrm{p}=\mathrm{m}\times \mathrm{v})$
2. The mass of the car is less than the mass of the truck, ${\mathrm{M}}_{\mathrm{car}}<{\mathrm{M}}_{\mathrm{truck}}$
3. If the momentum of car and truck is the same $({\mathrm{P}}_{\mathrm{car}}={\mathrm{P}}_{\mathrm{truck}})$ then the speed of the car is greater than the speed of the truck.$({\mathrm{V}}_{\mathrm{car}}>{\mathrm{V}}_{\mathrm{truck}})$.
4. This is because at constant momentum the mass is inversely proportional to the velocity of the object.

If a car and truck are moving with same momentum , the velocity of car is greater than the velocity of truck.
