Question

3 women push a stalled car. Each woman pushes with a 425 N force. What is the mass of the car if the car accelerates at 0.85 m/s2?

Answer 1

Given,

Force applied by 1 women = 425 N

Therefore,

Force applied by 3 women = 425 x 3 N = 1275 N

And,

Acceleration of car = 0.85 m/s^2

Now,

As per equation :-

=> F = ma

=> 1275 N = m x 0.85 ms^-2

=> (1275/0.85) Kg = m

=> m = 1500 kg

Hence, the mass of car = m = 1500 Kg

Answer 2

I’m going to assume that the three women are pushing in the same direction

Then this will be a one dimension motion

M = F/a = 3 x 425 / 0.85 = 1.5 kN

Feel free to ask for any clarification
