momentum.
net force.
weight.

3. What is conserved when two objects collide in a closed system?


acceleration
momentum
speed
velocity

4. What is the momentum of a 50-kilogram ice skater gliding across the ice at a speed of 5 m/s?

10 kg • m/s
500 kg • m/s
50 kg
250 kg • m/s

Answer 1

k hold on :)

Answer 2

momentum=mass∗velocity

Momentum is conserved in the second question.

For the last one, use the momentum formula :)

Answer 3

i got 250??

Answer 4

Yep

Answer 5
