Answer:
ac = 72 m/s²
Fc = 504 N
Explanation:
We can find the centripetal acceleration of the hammer by using the following formula:
where,
ac = centripetal acceleration = ?
v = constant speed = 12 m/s
r = radius = 2 m
Therefore,
ac = 72 m/s²
Now, the centripetal force applied by the athlete on the hammer will be:
Fc = 504 N
