First, find the work done. W = f*d, so 160 N * 1 m = 160 J. Then divide the work by the time to get the power. P = W/t. P = 160 J / 0.5 s = 320 W.
The answer is 320 W. Hope this helps, and have a great day! :)

Answer:

Please find here some hints :

Rule. Newton’s second law, or fundamental principle of dynamics, mentions that a resultant force exerted on an object is always equal to the product of the mass of that object by its acceleration. ... Each force applied to an object causes this object to accelerate in the direction of the force applied.

Is acceleration a force?

The acceleration force, sometimes called the inertia force, is the vehicle’s resistance to speed variations. It holds you back when you increase your speed and pushes you back when you slow down.

Calculating Velocity
m_a_m_a [10]

The average velocity of the object represented by the  distance time graph is 0.1\:meter\:per\:second

  • The velocity of an object is the change in the distance moved by an object with time.

  • This could also be related to the rate of change or slope of the graph.

  • Average velocity = \frac{change\:in\:distance}{change\:in\:time}

  • Average velocity = \frac{(5-0)}{(50-0}) = \frac{5}{50}=0.1\:meter\:per\:second

Therefore, the average velocity of the object is 0.1\:meter\:per\:second
