I need help with a physics question!

A pilot is flying a small plane at 56.6 m/s in a circular path with a radius of 188.5 m. The centripedal force needed to maintain the plane's circular motion is 1.89 x 10 to the 4th N. What is the plane's mass?

The plane's mass is 1111.76 kg. This is calculated using the formula of finding centripetal force; F = mv?/r, where F is the centripetal force, m the mass, v the velocity and r the radius. Find v? = 56.6*56.6 = 3203.56. Then, 3203.56 ? 188.5 = 16.995 = 17 rounded off. Therefore, 17m = 1.89 x 10^4. Divide both sides by 17to get a mass of 1111.76 kg.
