Physics

To calculate the average power delivered by the force acting on the object, we can follow these steps:

 

Calculate the work done on the object

The work done on the object is equal to the change in its kinetic energy. The object starts with an initial speed of 10 m/s and comes to a stop, so its final kinetic energy is zero.

 

The initial kinetic energy is given by:

where:

(mass of the object),

(initial speed).

 

Substitute the values:

So, the work done on the object is , as it comes to rest.

 

Calculate the time taken to come to a stop

To calculate the time, we use the kinematic equation:

where:

(initial velocity),
