Question

Сила сопротивления 18кН. Авто m-1,2т разгоняется до 72км/ч за 6сек. Определить силу тяги двигателя

Answer 1

F=m*a+Fc=m*V/t +Fc=1200*20/6+18000=22000 Н=22 кН

Answer 2

Calculation of Engine Thrust

To calculate the force of the engine thrust, we can use the formula:

Thrust = Mass x Acceleration

First, we need to convert the mass of the car from tons to kilograms. 1.2 tons is equal to 1200 kilograms.

Next, we need to calculate the acceleration of the car using the formula:

Acceleration = Change in Velocity / Time

Given that the car accelerates from 0 to 72 km/h in 6 seconds, we can convert the final velocity to meters per second and then calculate the acceleration.

Let's proceed with the calculations.
