I have a homework problem similar to 8.68 in HughYoung'sCollege Physics textbook yet im unsure how to includecoefficientsof friction between the bullet and block in my similarhomeworkproblem.
The problem is...
Force of 200N is needed to compress the spring by0.1meters.
A spring positioned horizontally, with one of its endsattachedto a wall. A 1 kg block is attached to the other endof the springand is resting on the horizontal surface.
A .01 kg bullet is fired horizontally towards the block andinthe collision the bullet is embedded into the block.Thecoefficient of friction between the block and horizontal surfaceis0.25. The maximal compression of the spring due to thecollisionis .025 meters.
Find the spring constant and initial velocity ofthebullet.
I found the spring constant to be 2000N/m byk=F/x k= 200N/0.1m = 2000N/m
I am unsure how to get initial velocity with frictionalsoplaying a part in this problem. If i could get help thatwouldbe great.
