Question

A particle is moving on a Circular path of radius 1m with 2m/s . If speed starts increasing at a rate of 2 m/s² , then acceleration of particle is .

1. 2m/s² 2. 4m/s² 3. 2√5m/s² 4. 8m/s²​

Answer 1

Answer:

2.4 m/s^2 is your answer

Answer 2

Answer: Option 3.

Explanation :

When an object goes in non uniform circular motion it has two linear accelerations.

1. Centripetal acceleration Ac = v^2/r

2. Tangential acceleration At = dv/dt

Net acceleration asked is resultant of these two vectors Ar & At
