First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 124 kg and the bag of tools has a mass of m, = 10.0 kg. The astronaut is moving away from the space station at v₁ = 2.10 m/s. What is the minimum final speed Ubf of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub.f= m/s

Balancing carefully, three boys inch out onto a horizontal tree branch above a pond, each planning to dive in separately.

When he starts to carry out his plan, at what precise moment does the branch break? Explain. Suggestion: Pretend to be the third boy and imitate what he does in slow motion. If you are still unsure, stand on a bathroom scale and repeat the suggestion.
