Question

A 68 kg runner exerts a force of 59N . what is the acceleration of the runner ?​

Answer 1

Answer:

Acceleration of the runner is = 0.9 ms⁻²

Explanation:

We Know That, Force, f = mass x acceleration.

                                ⇒ a = f/m

Given, mass = 68kg

 and , force = 59 N

           

∴ a = 59/68

a = 0.867 ms⁻²

a ≈ 0.9 ms⁻²

Answer 2

Concept:

An object having mass changes its velocity in response to a push or pull. Force is an external agent that has the power to alter a body's resting or moving condition. It has a size and a movement.

The rate at which the velocity of an object changes in relation to time is known as acceleration. They are accelerations and vector quantities. The direction of an object's acceleration is determined by the direction of the net force acting on it.

Given:

The weight of the runner is 68 kg and the force exerted by the runner is 59 N.

Find:

The acceleration of the runner.

Solution:

The mass of the runner, m = 68kg

The forces exerted by the runner, F =59N

Now, the force applied by an object is defined as the product of the mass and acceleration of the runner.

F = ma

59 = 68(a)

a = 0.867 m/s² = 0.9 m/s²

The acceleration of the runner is 0.9 m/s².
