Your car rounds a curve of 49 m radius at 8.2 m/s. What force is needed to keep your car turning in this circle if its mass
is 1083 kg? (this force is caused by the tire's friction with the road)

Respuesta :

MathPhys

Answer:

1500 N

Explanation:

Sum of the forces on the car in the radial direction:

∑F = ma

F = m v² / r

F = (1083 kg) (8.2 m/s)² / (49 m)

F ≈ 1500 N
