Question

a point moving in a circle of radius 25 cm and takes a time of 2revolutions per seconds find the acceleration​

Answer 1

Answer:

Explanation:

This being so,

radius r = 25 cm and frequency = 2 revolutions per second.

Radius = 25cm = 25100m=0.25m.

⇒ω=2π×2=4πrad/sec.  

Then the particle's acceleration is 4π2m/s−2

Answer 2

Explanation:

This being so, radius r = 25 cm and frequency = 2 revolutions per second. ⇒ω=2π×2=4πrad/sec. Radius = 25cm = 25100m=0.25m. Then the particle's acceleration is 4π2ms−2.
