Question

An automobile of mass 1500 kg has an initial velocity of 7.20 m/s toward the north and a final velocity of 6.50 m/s toward the west. The magnitude and direction of the change in momentum of the car are

Answer 1

Answer:

Explanation:

Momentum is the product of mass and velocity.

Momentum = mass * velocity

Given

Mass = 1500kg

resultant velocity

v² = 6.5²+7.20²

v² = 42.25+51.84

v² = 94.09

v = √94.09

v= 9.7m/s

Momentum = 1500*9.7

Momentum = 14550kgm/s
