To calculate the instantaneous speed, a very small space interval must be measured at a given time.
Explanation:
Given that,
Diameter of the wheel, d = 70 cm = 0.7 m
Initial angular speed,
Final angular speed,
Time, t = 4 s
(a) Angular acceleration,
(b) Tangential acceleration is :
Angular speed of the wheel after 2 seconds is :
Radial acceleration will be :
Hence, this is the required solution.
