Vehicle speed changes according to the law v = 0.5t. find the modulus of the resulting force acting

Vehicle speed changes according to the law v = 0.5t. find the modulus of the resulting force acting on it, if the mass of the car is 1 t.

To find the required modulus of the resulting force, we will use Newton’s second law: F = m * a = m * V ‘.

Functions and values of variables: m – vehicle weight (m = 1 t = 1 * 10 ^ 3 kg); V is the law of speed variation (V = 0.5t).

Let’s make a calculation: F = m * V ‘= 1 * 10 ^ 3 * (0.5t)’ = 1 * 10 ^ 3 * 0.5 * 1 = 500 N.

Answer: The modulus of the resultant force is 500 N.
