The speed of the car is 18.8 m/s
Explanation:
The variables that represent the givens are:
m = 2000 kg (mass of the car)
r = 30 m (radius of the curve)
t = 10 s (time elapsed to cover the curve)
The unknown is the speed of the car, which is given by:
where d is the distance covered by the car during the time t.
Here the car covers a circular trajectory of radius r, so the distance covered is
Therefore, the speed of the car is
