assuming no slippage of the wheels ...Hi everyone
New here so hope this is in correct place.
The question i have is as follows.
A train of mass 5 tonnes is trvelling with a velocity of 80 km h-1. If it needs to stop within a distance of 0.5 km using a constant braking force calculate:
A) deceleration of the train
b)the braking force required
c)the time taken to come to rest
d)The initial angular velocity of the wheels
e)the angular deceleration of the wheels
The wheels are 1.5m in diameter
I have done parts a b & c hopefully correct but am having trouble with parts d & e.
Any pointers in the right direction would be much appreciated
