Q1. A crate with mass 35.5 initially at rest on a warehouse floor is acted on by a net horizontal force of 120. What acceleration is produced?

Q2. A 18.00 kg lead sphere is hanging from a hook by a thin wire 3.60m long, and is free to swing in a complete circle. Suddenly it is struck horizontally by a 7.00kg steel dart that embeds itself in the lead sphere. What should be the least initial speed of the dart so that the combination makes a complete circular loop after the collision?
