Car AMass: 1,500 kgVelocity: 10 m/sCar BMass: 1,500 kgVelocity: 25 m/sCar CMass: 1,000 kgVelocity: 10 m/sWhich order shows decreasing momentum?A, B, CB, A, CC, B, A

Sagot :

Answer:

B, A, C

Explanation:

The momentum is equal to the mass times the velocity, so for each car the momentum is equal to

Car A

Momentum = Mass x Velocity

Momentum = 1,500 kg x 10 m/s

Momentum = 15,000 kg m/s

Car B

Momentum = Mass x Velocity

Momentum = 1,500 kg x 25 m/s

Momentum = 37,500 kg m/s

Car C

Momentum = Mass x Velocity

Momentum = 1,000 kg x 10 m/s

Momentum = 10,000 kg m/s

Then, the decreasing momentum is B, A, C because

37,500 is greater than 15,000 and 15,000 is greater than 10,000

So, the answer:

B, A, C
