Question

A force of 50n is required to push a car on a road level with constant speed of 10m/s .The mass of the car is 500 kg .What force should be applied to make the car accelerate at 1m/s2

Answer 1

We know the formula of Force, given by Newton,

$F = ma$

where F = Force, m = mass of the object and a = acceleration of the object.

We have been given the mass and the acceleration of the object,

$m = 500 kg\\a = 1 m/s^2$

We have to find the force to make a 500 kg car accelerate at 1 m/s^2.

Lets apply the formula,

$F = m*a$

$F = (500) kg * (1) m/s^2\\F = 500 kgm/s^2\\F = 500 N$

Thank you :)
