Vehicle speed changes according to the law vx = 10 + 0.5t. What is the modulus of the resultant

Vehicle speed changes according to the law vx = 10 + 0.5t. What is the modulus of the resultant force acting on the car if its mass is 1.5 tons?

To determine the desired modulus of the resultant force, apply Newton’s second law: F = m * a = m * V ‘.

Values of variables and functions: m – vehicle weight (m = 1.5 t = 1.5 * 10 ^ 3 kg); V is the law of speed change for a given vehicle (V = 10 + 0.5t).

Let’s perform the calculation: F = m * V ‘= 1.5 * 10 ^ 3 * (10 + 0.5t)’ = 1.5 * 10 ^ 3 * (0 + 0.5 * 1) = 750 N.

Answer: The modulus of the resultant force, according to the calculation, is 750 N.
