AI Thread Summary
A stuntman accelerates a dirt bike on a curved track with a radius of 7.50 m, starting from rest with a constant tangential acceleration of 2.35 m/s². The goal is to determine the time at which the total acceleration reaches 5.02 m/s². Participants in the discussion suggest calculating centripetal acceleration using the total and tangential accelerations to find the bike's velocity. There is a request for clearer working details to provide further assistance, emphasizing the importance of showing calculations for effective homework help. The conversation highlights the collaborative nature of solving physics problems in an educational context.

Homework Statement
A stuntman drives a dirt bike on a curved track with a radius of 7.50 m. If he starts from rest and accelerates at 2.35 m/s2, at what time will the magnitude of the total acceleration of the bike be 5.02 m/s2? (Hint: the tangential acceleration will stay constant at 2.35 m/s2.)

initial angular velocity: 0 rad/s
tangential acceleration: 2.35 m/s2 (constant)
radius=7.50 m
total acceleration=5.02 m/s^2

The attempt at a solution

What I have done thus far is find the centripetal acceleration using the total and tangential acceleration. Then I used the centripetal acceleration and the radius to find the velocity. But I am stuck what to do next, do I find alpha, omega? Any help would be very appreciated

Hi onetimeting. :welcome:

Please show your working to find the centripetal accelaration.

You can attach a clear image of a neatly handwritten page.

Without seeing your working, we are not able to help further. That is how the homework help works.
