My mind keeps thinking that there is some relationship between the displacement of the 2.5 m/s velocity of the first block after it left the spring. Is this something that is valid?
If a spring is originally compressed by 6cm, what is the force of the spring constant?
A block of inertia m=0.2kg is launched from a spring onto frictionless surface. The velocity is 2.5m/s upon leaving the spring.
I used Hooke's law and got
k=mg/x
0.2kg x 9.8m/s / 0.06m = 32.7 N/m
The next...
