Hi,
Could you please help me with the following problem I'm trying to solve without success:
John and Jim are racing around a circular track in sports cars. The track has a radius of 400 M. John is leading the race by half a lap and both cars are initially traveling at 60 M/s. Jim than begins to accelerate (acceleration not given). After 50 seconds Jim catches up with John. What was Jim's acceleration ?
Thank You

Since Jim is 200m behind John (0.5*400m) then covering that distance in 50s is going to be 200m/50s.

Thanks for your reply. Actually I should have said angular acceleration, not acceleration.

Sorry was in another window.
