A hiker climbs a hill 300m high.If she weighs 50kg,calculate the work she does in lifting her body to the top of the hill

F = mg = 50kg * 9.8N/kg = 490N.

W = Fd = 490N * 300m = 147,000 Joules.

Thankfully

Work= force x distance

Work= 50 x 300
Work= 15000J(Joules)

To calculate the work done by the hiker in lifting her body to the top of the hill, you can use the formula:

Work = Force * Distance

In this case, the force is equal to the weight of the hiker, which can be calculated using the equation:

Force = mass * gravity

The mass of the hiker is given as 50 kg, and the acceleration due to gravity is approximately 9.8 m/s^2.

Force = 50 kg * 9.8 m/s^2 = 490 N

The distance is given as the height of the hill, which is 300 m.

Now, we can calculate the work done by substituting these values into the formula:

Work = 490 N * 300 m = 147,000 Joules

Therefore, the work done by the hiker in lifting her body to the top of the hill is 147,000 Joules.
