Question

A 1700 kg car drives around a flat 170-m -diameter circular track at 27 m/s.

What is the magnitude of the net force on the car?

Answer 1

the magnitude of the net force on the car is 144,270 N.

Step-by-step explanation:

To solve this problem, we need to use the formula for centripetal force:

F = (m * v^2) / r

where F is the net force, m is the mass of the car, v is the speed of the car, and r is the radius of the circular track (which is half the diameter).

First, we need to find the radius of the track:

r = d/2 = 170 m / 2 = 85 m

Now we can plug in the values we know:

F = (1700 kg * (27 m/s)^2) / 85 m

F = 144,270 N

Therefore, the magnitude of the net force on the car is 144,270 N.
