Caleb is swinging Rachel in a circle with the Centripetal force of 533N. If the radius of the circle is 0.75m and Rachel has a mass of 16.4kg, how fast is Rachel moving? Round to the nearest tenth.


Answer: 4.9 m/s
Why? I just took the test ;)

Answer:

Correct answer:  v = 4.937 m/s

Explanation:

The formula for calculating the centripetal force is:

F = m · v²/r

where m is the mass, v is the tangential velocity,  r is the radius

v = √(F · r)/ m = √(533 · 0.75)/ 16.4 = 4.937 m/s

v = 4.937 m/s
