A 400kg sports car collides with a stopped pickup 40m/s. After the collision, the sports car stops and the pickup moves forward at 15m/s. What is the momentum of the sports car before the collision?
P=mv
= 400kg x 40m/s
To find the momentum of the sports car before the collision, we can use the formula:
Momentum = Mass × Velocity
Given:
Mass of the sports car (m) = 400 kg
Velocity of the sports car before the collision (v) = 40 m/s
Substituting these values into the formula, we get:
Momentum = 400 kg × 40 m/s
Momentum = 16,000 kg⋅m/s
Therefore, the momentum of the sports car before the collision is 16,000 kg⋅m/s.
