Homework Statement
A rocket of force 1000N is propelled upwards by a thrust of 1800N. The air resistance is 500N.
a) Work out the resultant force on the rocket.
A bungee jumper of mass 60kg jumps from a bridge tied to an elastic rope which becomes taut after he falls 10m. Consider the jumper when he has fallen another 10m and is traveling at 15 m/s.
A) Work out how much energy is stored in the rope. Take g= 10 m/s squared and ignore air resistance.
Homework Equations
E = mgh
The Attempt at a Solution
1)a)
1000N+1800N - 500N = 2300N
2)a)
60*10*10 = 6000J
