(Question)

A crane released a block of mass (m) 5.0 kg from a height (h) of 2.0 meters towards a spring with spring constant of k 85 N/m as shown in the figure. Air resistance with a magnitude of 30.0 N acts on the block as it moves through the vertical height of (h).

 

-By how many meters was the spring compressed?

 

-What is the velocity of the block just as it touches the spring?
