Answer:

750W

Explanation:

Given parameters:

Weight = 1 x 10³N = 1000N

Distance  = 1.5m

Time  = 2s

Unknown:

Power = ?

Solution:

Power is the rate at which work is done

  Work is the force applied on a body to move it through a particular distance

         Work = force x distance

            Power = \frac{work}{time}

Now, work = 1000 x 1.5 = 1500J

So;

     Power  = \frac{1500}{2}   = 750W

Describe each of Newton’s Laws of Motion in ice skating. What can you design/develop to improve ice skating?
denis23 [38]

Newton's three laws of motion can be used to describe the motion of the ice skating.

<h3>Newton's first law of motion</h3>

Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force.

  • Based on this law, once the ice skating starts, it will continue endlessly unless external force stops it.

<h3>Newton's second law of motion</h3>

Newton's second law of motion states that the force applied to an object is directly proportional to the product of mass and acceleration of an object.

  • Based on this law, the force applied to the ice skating is equal to the product of mass and acceleration of the ice skating.

<h3>Newton's third law of motion</h3>

This law states that action and reaction are equal and opposite.

  • Based on this law, the force applied to the ice skating is equal in magnitude to the reaction of ice.
