A wheel is fixed at its centre and has a radius of 0.7m. At t=0, a point on the rim of the wheel is at theta=0, and is not moving but is subject to constant angular acceleration of a=0.5 rad/s^2. For 10 seconds, find:
a) angular displacement (theta)
b) the tangential velocity of a point on the rim at this time
c) the tangential acceleration of a point on the rim

Question

A wheel is fixed at its centre and has a radius of 0.7m. At t=0, a point on the rim of the wheel is at theta=0, and is not moving but is subject to constant angular acceleration of a=0.5 rad/s^2. For 10 seconds, find:
a) angular displacement (theta)
b) the tangential velocity of a point on the rim at this time
c) the tangential acceleration of a point on the rim

sounds like integration may be involved.

amistre64 · Answer

a(t) = a
v(t) = at + C
s(t) = at^2/2 + Ct + K
