Question

A stalled car is pushed with a force of 342N from rest. How far does the car travel in 12 seconds if it’s mass is 989kg

Answer 1

24.89m

Explanation:

Given parameters:

Force on car = 342N

Initial velocity = 0

Time taken = 12s

Mass of the car = 989kg

Unknown:

Distance covered by the car = ?

Solution:

To solve this problem, we simply use one of the appropriates equations of motions.

                     s = ut + $\frac{1}{2}$at²

   s is the distance

    u is the initial velocity

    t is the time taken

    a is the acceleration of the car.

To find the acceleration;

       Acceleration = $\frac{Force }{mass}$ = $\frac{342}{989}$

          Acceleration = 0.35m/s²

Inputting the parameters in the equation:

           s = 0 x 12 + $\frac{1}{2}$ x 0.35 x 12² = 24.89m
