• ### Physics Problem !!!!!!!!!!!!!!!!!!!!!!!!!11?

You have been asked to design a “ballistic spring system” to measure the speed of bullets. A bullet of mass is fired into a block of mass . The block, with the embedded bullet, then slides across a frictionless table and collides with a horizontal spring whose spring constant is . The opposite end of the spring is anchored to a wall. The spring’s maximum compression is measured.

What was the speed of a 5.7 bullet if the block's mass is 2.3 and if the spring, with , was compressed by 12 ?

• ### Physics Rotational Question!!!!!!!!!!?

A turbine spinning with angular velocity w_0 rad/sec comes to a halt in T seconds. Find an expression for the angle delta theta through which the turbine turns while stopping.
