It would be kinetic energy. Let's say the book is weighs 10 Newtons you need to use a force of 10 Newtons to lift the book. In other words it's positive. As you move the book you're giving it energy. Namely potential energy which will turn to kinetic energy if you let it go. So you're changing it's position and energy.

How to convert from fahrenheit to celsius
kaheart [24]
The formula for Fahrenheit and Celsius conversion is 
T(°F)<span> = </span>T(°C)<span> × 1.8 + 32
where T is temperature in F or C ( Fahrenheit or Celsius whatever is the case)
</span>This means that keeping this FORMULA in mind we can add different values to it and  accordingly convert values from one to another.
Some examples of fahrenheit conversions to Celsius are :
32°F = 0°C  using F = (0 x 1.8) + 32

The  power the swimmer must provide to overcome that drag force is 50 W.

<h3>What is work done?</h3>

Work done is equal to product of force applied and distance moved.

Work = Force x Distance

Given is  an athlete, swimming at a constant speed, covers a distance of 203 m in a time period of 5 minutes and 50 seconds = 350 seconds. The drag force exerted by the water on the swimmer is 86.0 N.

Work done by drag force is  W= F x d

So, W = 86 N x  203 m

W = 17.458 kJ

Power , a swimmer is provided P = Work done/ Time

P = 17458 / 350

P = 50 W

Thus, the power, the swimmer must provide to overcome that drag force is  50 W.
