Question

An Inuit pushes a loaded dogsled with a mass of 600.0 kg over the frictionless surface of hard-packed snow. He exerts a constant 150.0 N force as he does so.

What is the sled's acceleration?

Answer 1

Given parameters:

Mass of Dogsled = 600kg

Force = 150N

Unknown:

Acceleration of the sled = ?

Solution:

Force is a physical quantity and can be expressed as a product of mass and acceleration.

Force = mass x acceleration

Since acceleration is unknown, we input the parameters and solve for it;

150 = 600 x acceleration

Acceleration =
`(150)/(600)` = 0.25m/s²

The acceleration of the sled is 0.25m/s²
