At t1 = 1.00 s, the acceleration of a particle moving at constant speed in counterclockwise circular motion is At t2 = 2.00 s (less than one period later), the acceleration is The period is more than 1.00 s. What is the radius of the circle?

meters

Explanation:

See the remaining part of required information in the attached image

Solution

The formula for calculating velocity is equal to

Where v is the velocity, are time range for two acceleration vectors and angle between two acceleration vector respectively and r is the radius of the circle

Putting the give values in above equation we get

Acceleration is equal to

Radius is equal to

Putting the given values we get -

we need to know the time interval during which the force acts. impulse of force = momentum change
