Question

what is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5m/s2

Answer 1

F = ma

m = F/a
= 14000 / 5
= 2800 kg

Mass of truck is 2800 kg

Answer 2

Concept:

Force is the push or pulls that alters the velocity of a mass-containing item.

Mathematically force is expressed as, F = ma

Given:

Force = 14,000 N

Acceleration = 5m/s²

Find:

We need to determine the mass of the truck.

Solution:

• Force is the push or pulls that alters the velocity of a mass-containing item.
• Whether a body is in motion or at rest, an outside force has the power to alter its position.
• There is a direction and a magnitude to force. The force is applied at the point of application and in the direction indicated by the force.

We know, force = mass × acceleration

F = m.a

Therefore, m = F/a

m = 14,000/5

m = 2,800 kg

Thus, the mass of a truck is 2,800 kg.
