Question

A hockey puck with a mass of 0.12 kg is traveling across the ice at a velocity of 150 m/s downfield. What is the momentum of the

hockey puck? (1 point)
OM 18 kg* m/s
OP 8*10-4 kg * m/s
OP 18 N
O P = 18 kg* m/s

Answer 1

(Question) Which of the following best describes the sum of all forces acting on an object?

(Answer) net force, which is a vector sum

(Question) Suppose a man is sitting on a chair and exerting 100 N of force downward, while a spring beneath the chair exerts 150 N of force upward. If you assign a negative value to the downward force, what is the net force of this system?

(Answer) 50 N

(Question) During a game of pool, a cue ball travels to the left with 70 N of force and collides with the four ball moving with a force of 50 N to the right. If you assign a negative value to the force moving to the right, what is the net force of this system?

(Answer) 20 N

(Question) Recall that the formula for momentum is: P=mv Which of the following correctly shows momentum being calculated?

(Answer) 45 kg*m/s=(9 kg) (5 m/s)

(Question) A hockey puck with a mass of 0.12 kg is traveling across the ice at a velocity of 150 m/s downfield. What is the momentum of the hockey puck?

Hey there! Lets begin!

1. Which of the following best describes the sum of all forces acting on an object?

• Net force, which is a vector sum.

2. Suppose a man is sitting on a chair and exerting 100 N of force downward, while a spring beneath the chair exerts 150 N of force upward. If you assign a negative value to the downward force, what is the net force of this system?

• 50 N

3. During a game of pool, a cue ball travels to the left with 70 N of force and collides with the four ball moving with a force of 50 N to the right. If you assign a negative value to the force moving to the right, what is the net force of this system?

• 20 N

4. Recall that the formula for momentum is:

P=mv

Which of the following correctly shows momentum being calculated?

• 45 kg * m/s = (9 kg)(5 m/s)

_______________________________________________________

5. A hockey puck with a mass of 0.12 kg is traveling across the ice at a velocity of 150 m/s downfield. What is the momentum of the hockey puck?

• P = 18 kg * m/s
