A car with a mass of 500 kg, accelerating from a standstill, reached a speed of 20 m s in 10 s.

A car with a mass of 500 kg, accelerating from a standstill, reached a speed of 20 m s in 10 s. What is the resultant of all forces?

Let us recall the formula for finding the value of the resultant forces:

F = m * a;

We will be given all the quantities, except for a. Let’s find a:

a = v – v0 / t;

a = 20 – 0/10;

a = 2 (m / s ^ 2);

Now let’s find F:

F = 500 * 2;

F = 1000 (H);

Answer: the resultant of all forces is 1000 N.
