Question

Julius competes in the hammer throw event. The hammer has a mass of 7.26 kg and is 1.215 m long. What is the centripetal force on the hammer when it has a tangential speed of 31.95 m/s? The answer is rounded off to the nearest whole number. 190 N 840 N 1,400 N 6,100 N

Answer 1

6,100 N

Step-by-step explanation:

Answer 2

In the circular motion of the hammer, the centripetal force is given by

`F=m (v^2)/(r)`
where m is the mass of the hammer, v its tangential speed and r is the distance from the center of the motion, i.e. the length of the hammer.
Using the data of the problem, we find:

`F=m (v^2)/(r)=(7.26 kg) ((31.95 m/s)^2)/(1.215 m)=6100 N`
