Question

A lorry with a mass of 5000 kg accelerates to overtake a caravan on the motorway. Its acceleration is 1.5 m/s². What force must the engine be providing? You can ignore the effects of friction and air resistance.

Answer 1

7500 Newtons

Step-by-step explanation:

Newton's second law tells us that F = ma.

We know that:

m = 5,000 kg, and

a = 1.5 m/s^2

Then we can calculate force, F:

F = (5000 kg)*(1.5 m/s^2)

F = 7500 kg*m/s^2 or 7500 Newtons
