Elaborate please

It's from my textbook

That's the thing, I din't know what do with it. That's why I'm here for help.

1. Homework Statement A bullet of mass m is fired into a block of mass M initially at rest on a frictionless table of height h. The bullet remains m in the block, and after impact the block lands a distance d from the bottom of the table. Determine the initial speed of the bullet. 2...

I used (m +M)gh for the potential energy and set that equal to the kinetic energy ½(m + M)v₂² and found that v₂ = √(2gh). And since it was a completely inelastic collision (right?) I used mv₁ = (m + M)v₂ → v₁ = (m + M)v₂ * 1/m Is this right?

When I use the conservation of energy equation, do I account for T on both sides?

Thanks.. but I still don't quite see how to obtain the solution.

Homework Statement A ball whirls around in a vertical circle at the end of a string. The other end of the string is fixed at the center of the circle. Assuming that the total energy of the ball-Earth system remains constant, show that the tension in the string at the bottom is greater than the...
