1. A student athlete is participating in the hammer throw. The student rotates in uniform circular motion with the mass rotating 4.5m away from the center of the rotation
4.5m
Refer to the above information and diagram. The student athlete can rotate so that the
Object is moving with a speed of 15 m/s.
What is the acceleration for this uniform circular motion?

Explanation:

In uniform circular motion, the acceleration of the object is due to the changing direction of velocity of the object. this acceleration is referred to as centripetal acceleration. It can be calculated by following formula:

where,

ac = centripetal acceleration = ?

v = speed of the object = 15 m/s

r= radius of circular motion = distance of object from center of rotation = 4.5 m

Therefore, using these values in equation, we get:

insects!
