A car with a mass of 1.2 t begins to move horizontally with an acceleration of 1.04 m / s What is the traction force of a car if the coefficient of friction is 0.2
According to Newton’s second law: Frav. = ma
On the OX axis:
Ftraction – Ftr. = ma
On the OY axis:
N = mg,
Since Ftr. = MN, then we get:
Fthroat = m (a + Mg), substitute the numbers and get:
Fthrust = 14880N = 15kN
