Traveling at 6 cm/sec, how long does it take the wheel to complete one rotation

[From: ] [author: ] [Date: 12-06-16] [Hit: ]
4159/6 = 5.24 seconds.The question is too simple, the length of the ramp and height of the ramp do not matter,as we have to assume the wheel is able to complete at least one revolution. Are you sure the question is correct?......
A wheel with radius 5 cm is being pushed up a ramp at a rate of 6 cm per second. The ramp is 680 cm long, and 230 cm tall at the end

what formula do i use?

I know it travels 31.415 in one rotation (2 times pi times radius) but how do I determine this?

time = ditance/velocity = 31.4159/6 = 5.24 seconds.

You just have to divide the circumference (31.415cm) by the speed (6cm/s) and you get the time = 5.236 seconds (3 d.p.)

Hope this helps

please provide the exact question . what is to be determined?
