Answered

Two cars, each having a mass of 1,000 kg are being tested at the Department of Highway Safety facility. Car A is moving at 30 m/s to the north. Car B is moving at 15 m/s to the south. When they collide, which of the following is true?

a Car A applies a greater force on car B than car B applies on car A.

b Car A applies a force on car B equal to the force car B applies on car A.

c Car B applies a greater force on car A than car A applies on car B.

d Car A and car B do not have the same velocity; you cannot compare the forces.



Answer :

When Car A moving at 30 m/s to the north and Car B moving at 15 m/s to the south collide Car A applies a greater force on car B than car B applies on car A.

p = m v

p = Momentum

m = Mass

v = Velocity

For car A,

m = 1000 kg

v = 30 m / s

p = 1000 * 30

p = 30000 kg m / s

For car B,

m = 1000 kg

v = 15 m / s

p = 1000 * 15

p = 15000 kg m / s

F = dp / dt

Force can also said as the rate of change of momentum. Since the momentum of car A is higher than that of car B, the force applied by car A on car B will he higher

Therefore, car A applies a greater force on car B than car B applies on car A.
