Answer 1

Question :

One truck having a mass of 975kg is initially at rest. In 20 seconds, the truck attains the velocity of 40m/s. Calculate the amount of net force acting on the truck.

Given :

Mass of the truck, m = 975 kg

Time taken, t = 20s

Initial velocity, u = 0m/s

Final velocity, v = 40m/s

To find :

Force acting on the truck.

Solution :

$acceleration \: = \: \dfrac{v \: - \: u}{t}$

$\implies$ $\dfrac {40 \: - \: 0}{20}$

$\implies$ $\dfrac {40}{20}$

$\implies$ $\bold {2}m/s^2$

Now,

Force = $\boxed {mass \: × \: acceleration}$

$\implies$ 975 × 2

$\implies$ 1950N
