A car with a mass of 1.2 tons moves from a standstill with an acceleration of 0.8 m / s 2.

A car with a mass of 1.2 tons moves from a standstill with an acceleration of 0.8 m / s 2. What is the thrust force of the engine if the friction force is 0.02.

Given:
m = 1.2 t
a = 0.8 m / s
Ftr = 0.02
To find:
pulling force
Decision:
Let’s substitute these tasks into the formula, not forgetting to convert the mass of tons to kilograms (1t = 1000kg)
Ft = 1200 (0.02 * 10 + 0.8) = 1200N
Answer: 1200N
