Defiance drake, space adventurer, desperately needs to reach a cargo vessel 100m away, or run out of air and die in deep space. for our purposes, there are two relevant directions, the direction defiance is traveling in (the x-direction, at 1 m/s), and direction of the cargo ship's motion, which is perpendicular to her motion (y-direction, 10 m/s). defiance uses her jet boots, choosing to accelerate directly in the x-direction at 0.25g (she starts at (x=100,y= if the cargo vessel is 25 m long, and its nose cone starts at x=0,y=0, will defiance reach the ship or miss? if she misses, how should she have chosen her path (assume she cannot exceed 1 g)?

Amass m = 74 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius r = 18.4 m and finally a flat straight section at the same height as the center of the loop (18.4 m off the ground). since the mass would not make it around the loop if released from the height of the top of the loop (do you know why? ) it must be released above the top of the loop-the-loop height. (assume the mass never leaves the smooth track at any point on its path.) 1. what is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? 2. what height above the ground must the mass begin to make it around the loop-the-loop? 3. if the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? 4. if the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the final flat level (18.4 m off the ground)? 5. now a spring with spring constant k = 15600 n/m is used on the final flat surface to stop the mass. how far does the spring compress?
