Determine the acceleration of the car if its mass is 2.9 tons, the traction force is 650kN,

Determine the acceleration of the car if its mass is 2.9 tons, the traction force is 650kN, and the coefficient of friction is 0.007.

Initial data: m (mass of a moving vehicle) = 2.9 t (2.9 * 10 ^ 3 kg); F (pulling force) = 650 kN (650 * 10 ^ 3 N); μ (coefficient of friction) = 0.007.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

The acceleration of the car is determined by the formula: m * a = F – Ftr. = F – μ * N = F – μ * m * g, whence a = (F – μ * m * g) / m.

Calculation: a = (650 * 10 ^ 3 – 0.007 * 2.9 * 10 ^ 3 * 10) / (2.9 * 10 ^ 3) ≈ 224 m / s2.

Answer: The car was moving with an acceleration of 224 m / s2.
