Gregg Reid of Atlanta, Georgia, built a motorcycle that is over 4.5 m long and has a mass of 235 kg. The force that holds Reid and his motorcycle in a circular path with a radius of 25.0 m is 1850 N. What is Reid’s tangential speed? Assume Reid’s mass is 72 kg.

Answer :

With Georgia's motorcycle at over 4.5 m long and having a mass of 235 kg, Reid’s tangential speed is mathematically given as

vt=12.4m/s

What is Reid’s tangential speed?

Generally, the equation for the Conservation of momentum is mathematically given as

mn=m1+m2

Therefore

mn=235+72

mn=307

Therefore

Fc=mn*a

THerefore

[tex]vt=\sqrt{\frac{rFc}{mn}}\\\\vt=\sqrt{\frac{25*1850}{307}}[/tex]

vt=12.4m/s

In conclusion, The tangential speed is

vt=12.4m/s

Final answer:

To find Gregg Reid's tangential speed, the centripetal force formula is used, showing that Reid's tangential speed is approximately 12.27 m/s.

Explanation:

The question asks for the tangential speed of Gregg Reid's motorcycle and himself, moving in a circular path based on the centripetal force provided. Using the formula for centripetal force F = mv²/r, where F is the centripetal force, m is the mass, v is the tangential speed, and r is the radius of the circular path, we can solve for the tangential speed v. Given F = 1850 N, total m (mass of Reid + motorcycle) = 235 kg + 72 kg = 307 kg, and r = 25.0 m:

v = √(Fr/m) = √(1850 * 25.0 / 307) = √(150.489) ≈ 12.27 m/s

Therefore, Gregg Reid's tangential speed is approximately 12.27 m/s.
