Homework Statement
A parachutist with mass m = 70 kg jumps from an airplane traveling at a speed v = 100 km/h at a height H = 2500 m and lands with a speed vf = 5.00 m/s. Use the “conservation of energy strategy” to calculate the change in internal energy of the system from just after the jump until just before landing. (1E6)
Homework Equations
PE+KE=PE[f]+KE[f]
The Attempt at a Solution
I'm thinking that where it talks about the airplane traveling at 100 km/h makes no difference in this problem. So the actual initial velocity would be vi=0km/h then I think I would calculate the velocity without Air Resistance and then factor in the difference of speed. Am I headed in the right direction.
