Answer:


Explanation:
m = Mass rocket = 1070 kg
v = Velocity of rocket = 3.75 m/s
a = Acceleration of rocket = 5g
g = Acceleration due to gravity = 
The energy balance of the system is given by

The force balance of the system is given by

The distance the spring must be compressed is 

The force constant of the spring is
.
Hi , a class 2 lever has the load between the force and the fulcrum .So a stapler is a good example.
