| **The speed of the car changes according to the law V = 0.3t, its mass is m = 3t a) Find the acceleration of the car b) Find the resulting force acting on it**

The law of speed change from acceleration:

V = a * t, therefore, in the formula given to us in the condition, 0.3 is acceleration. According to Newton’s law F = ma = 0.3 * 3000 = 900Н
