Question

A force of 500N is needed to accelerate an empty truck to 10m/s squared. What is the mass of the truck.

Answer 1

Newton's 2nd law says Force = mass times acceleration (F = ma). If both sides of this equation are divided by "a" then we get:

F/a = ma/a

F/a = m

So, since F (force) = 500 N and acceleration (a) = 10 m/s² then:

500/10 = 50 kg
