Answer:
B
Explanation:
When something is moving at a constant velocity it's called the centripetal force. And the centripetal force accelerates radially outwards. It's like an ambulance siren. the sound waves are being exerted out into the atmosphere radiallly.
Answer:
m1v1=m2v2, v2=4.3m/s KE=(0.5)(2.94)(4.3)=6.2J
B, is the answer to the question
Answer: 21 kg x m/s
Momentum can be found using the equation p = mv, or momentum = mass times velocity.
Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)
Solve the equation to get a momentum of 21kg x m/s
