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

Respuesta :

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

Answer:

A 24 km/hr is correct
