Answer :
Final answer:
The energy dissipated by the resistance of the medium is 68600 Joules.
Explanation:
To calculate the energy dissipated by air resistance, we can use the formula:
Energy = force x distance
In this case, the force is equal to the weight of the parachutist, which can be calculated using the formula:
Force = mass x acceleration due to gravity
Given that the mass of the parachutist is 70 kg and the acceleration due to gravity is 9.8 m/s^2, we can calculate the force:
Force = 70 kg x 9.8 m/s^2 = 686 N
Now we can calculate the energy dissipated by multiplying the force by the distance:
Energy = 686 N x 100 m = 68600 Joules
