Question

A car accelerates at a constant rate of 1.83m/s2 along a flat straight road. The force acting on the car is 1.870 kN. Calculate the mass of the car.

Answer 1

1021.85 kg

Explanation:

F= 1.870kN

=1.870×1000N

=1870N

a=1.83m/s2

since F=m .a therefore

m=F/a= 1870/1.83

=1021.85 kg

Answer 2

Answer:

Given:

acceleration=1.83m/s²

Force=1.870kN

=1870N

We also know that :

Force = mass × acceleration

so,

Mass = Force/ acceleration

=1870/1.83

=1020 kg

Hence, mass of the car is 1020 kg.
