Question

ПОМОГИТЕ, ОЧЕНЬ СРОЧНО, SOOOS!!! автобус масса которого равна 15 т трогается с места с ускорение 0,7м/c найти силу тяги если сила трения равна 500Н

Answer 1

Начальная скорость равна 0, теперь переводим единицы измерения,  15 тонн= 15.000 кг, F1- это сила трения, F2- это сила тяги нужно найти равнодействующую, R=ma, R= 15.000*0,7=10.500, F2= R-F2, F2= 10.500-500= 10.000 H или 10 кН

Answer 2

Calculation of the Traction Force

To find the traction force of the bus, we need to consider the forces acting on it. The two main forces involved are the force of traction and the force of friction.

The force of traction is the force that propels the bus forward, while the force of friction opposes the motion of the bus. In this case, the force of friction is given as 500 N.

The equation that relates force, mass, and acceleration is:

Force = Mass x Acceleration

Given: - Mass of the bus = 15 t = 15,000 kg - Acceleration = 0.7 m/s^2 - Force of friction = 500 N

Substituting the given values into the equation, we can calculate the traction force:

Force = 15,000 kg x 0.7 m/s^2

Calculating this, we find:

Force = 10,500 N

Therefore, the traction force of the bus is 10,500 N.
