Hi all you geniuses, I've got a bit of a dilemma, I'm not the best at physics. Oh well. Anyways, I was wondering if anyone out on the forums could help me with a few problems. If you choose to help it would be greatly appreciated, and I don't need the math work all written out, just answers. Thanks!

1. It takes 20 seconds for a 600-kg racing car to travel at a uniform speed around a circular racetrack of 50 m radius. What average force must the car's tires exert against the track to maintain its circular motion?

2.A player kicks a soccer ball from the level ground with a velocity of 36 m/s at an angle of 40 above the horizontal.

a) What is the "hang time" of the ball? ( time ball is in the air )
b) The distance the ball travels before it hits the ground.
c) The ball's maximum height.


Thanks for helping!

Like seriously give me 10 minutes to dig out my physics binder and find the book that I call notes because I think I can help you.

2. A. 4.72 seconds
B. 130.24 m
C. 27.32 m

I'll try to help with number one.

Also, would you like to see the work?

Hope I helped. I am in AP Physics so this was some much needed review for me.

I think I could work with that.

Fc = MV^2/R
Also if you want I can send you a message with all the equations I used.
