Question

What is the acceleration of a 1000 kg vehicle if its engine gives off a force of 5000 newtons

Answer 1

We know that F=ma

Therefore, a = F/m

F=5000N and m=1000kg

Therefore a=5000/1000

=5m/s^2

Answer 2

Concept:

• We need to understand what is force
• Force is described in physics as the push or pull that causes a massed object to change its velocity.
• Force is an external agent that has the power to alter a body's resting or moving position. It has a direction and a magnitude.
• The fundamental equation of motion in classical mechanics is Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration of its centre of mass, or F = ma.

Given:

• The mass of the vehicle m = 1000 kg
• The force provided by the engine F = 5000 N

Find:

• The acceleration of the 100kg vehicle

Solution:

• Force is the product of mass and acceleration of the body
• F = ma
• 5000 N = 1000 *a
• a = F/m
• a = 5000 N/ 1000kg
• a = 5 m/s^2

The acceleration of the 1000kg vehicle is 5m/s^2.
