Question

A go kart is traveling at a constant 13.8 meters per second around a horizontal circular track with a radius of 42.0 meters. The Combined mass of a go kart and the driver is 143 kg. What is the magnitude of the centripetal force acting on the combined mass

Answer 1

Answer:

648.40N

Explanation:

Centripetal acceleration is the acceleration of an object around a circular path. Centripetal for e acting on the combined mass is expressed as:

F = ma

F = mv²/r

m is the mass of the object = 143kg

v is the linear velocity = 13.8m/s

r is the radius = 42.0m

Substitute the given parameters into the formula;

F = 143*13.8²/42

F = 27,232.92/42

F = 648.40N

Hence the magnitude of the centripetal force acting on the combined mass is 648.40N
