A790kg car moving at 7 m/s takes a turn around a circle with a radius of 20 m. determined the net force (in newton’s) acting upon the car.

1935.5 N is the "net force" acting on a car.

Explanation:

Given that,  

Mass of the car is 790 kg.

Velocity of the car is 7 m/s. (v)

It turned around with 20 m. (r)  

We know that, Net force = m × a

Now, Net force = m × a

Net force = 790 × 2.45

Net force = 1935.5 N
