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
[tex]\text { Here, acceleration of the car is radial acceleration } a_{\mathrm{rad}}=\frac{v^{2}}{r}[/tex]
[tex]\mathrm{a}_{\mathrm{rad}}=\frac{7^{2}}{20}[/tex]
[tex]\mathrm{a}_{\mathrm{rad}}=\frac{49}{20}[/tex]
[tex]a_{\text {rad }}=2.45 \mathrm{m} / \mathrm{s}^{2}[/tex]
Now, Net force = m × a
Net force = 790 × 2.45
Net force = 1935.5 N
