A soccer player kicks a ball, changing its momentum by 11 kg. M/s, The net force on the ball is 910 N. How long does the soccer player maintain contact with the ball?

Contact maintained by the soccer player, with the ball is of 0.01 seconds.

Explanation:

Given:

Change in momentum of the ball, Δp =

Net applied force on the ball, F =

We have to find for how long the soccer player maintains contact with the ball.

Formula to be used:

Acceleration = Ratio of change in velocity and time.

⇒

⇒

Momentum = Product of mass of an object and applied time.

⇒

⇒    ..plugging

⇒      ..Newtons seconds law,

⇒         ..re-arranging the equation.

Plugging the value of force and momentum we have.

⇒

⇒

⇒ sec

So,

The soccer player maintain contact with the ball for 0.01 seconds.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
