Question

Five men push a stalled car with an average force of 400 N per person. Find the mass of the
car if the car accelerates at 1 m/s.​

Answer 1

The mass of the car is 2000 kg

Explanation:

We can solve this problem by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:

$\sum F = ma$

where

$\sum F$ is the net force

m is the mass

a is the acceleration

In this problem, we have:

$a=1 m/s^2$ is the acceleration of the car

Each person applies a force of 400 N, and there are five men, so the total force applied is

$\sum F = 5\cdot 400 N = 2000 N$

Therefore, the mass of the car is:

$m=\frac{\sum F}{a}=\frac{2000 N}{1 m/s^2}=2000 kg$
