Homework Statement
A block of mass m = 0.1 kg is connected to a spring of unknown spring constant k. It is compressed to a distance x from its equilibrium position and released from rest.
After approaching half the distance (x/2) from equilibrium position, it hits another block and comes to rest momentarily, while the other block moves with a velocity 3 m/s. The total initial energy of the spring is:
1.5 J
0.6 J
0.3 J
0.8 J
Homework Equations
Spring potential energy is 1/2 kx2
In this question we have to do basically energy balance
The Attempt at a Solution
Isn't this question wrong?
We should be given other block mass and told that it is an elastic collision?
