Acompact car with a mass of 725 kg is moving at 30 m/s. what is its momentum?

21750 kg m/s

Explanation:

Momentum of a body is the product of its mass and velocity. Momentum is a vector quantity. The rate of change of momentum gives the net force. Momentum for more than one particle is given by

m = Mass of car = 725 kg

v = Velocity of car = 30 m/s

Momentum for a single object

p = m×v

⇒p = 725×30

⇒p = 21750 kg m/s

∴ The momentum of the compact car is 21750 kg m/s

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

increase masses, decrease separation
