## ikshjbdckoj 2 years ago Someone Help me!!!! Please!!! 2. The product of an object’s mass and velocity is its centripetal force. 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

k hold on :)

2. Shane_B

momentum=mass∗velocity Momentum is conserved in the second question. For the last one, use the momentum formula :)

3. ikshjbdckoj

i got 250??

4. Shane_B

Yep

5. ikshjbdckoj

ohhhhhh I didn't see that 250 was a chioce! haha

6. ikshjbdckoj

You don't know the other two?

7. BoneFreeze

Momentummo entum you know the answer. Actually you could do it yourself, just read few lines in wikipedia.

8. ikshjbdckoj

I didn't know this. They're confusing... It seems like they could be any one of them.

9. Shane_B

I gave you the other two...read :)

10. BoneFreeze

*momentum *momentum *you... (phone typing,sorry)

11. ikshjbdckoj

ohhhhhh... didn't see that. I'm sorry ya'll I've been like losing my mind today!!

12. Shane_B

s'ok :)

13. ikshjbdckoj

haha thanks :)
