Suppose a cars momentum is calculated to be 36000 kg• km/ hr the mass of the car is 1500 kg what is the magnitude of the velocity of the car? a) 24 km/hr b) 0.042 km/hr c) 37,500 km/hr d) 34,500 km/hr

Momentum = (mass) x (speed)

(Speed = magnitude of velocity)

36,000 kg-km/hr = (1,500 kg) x (speed)

Divide each side by (1,500 kg) :

Speed = (36,000 kg-km/hr) / (1,500 kg)

Speed = (36,000 / 1,500) kg-km / hr-kg

Speed = 24 km/hr

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

gravity
