You have a powerful spring whose stiffness is 2 X 10^5 N/m with a relaxed length of 50cm, which you want to use to launch a package of mass 1kg. If you compress the spring to 30cm
a)what will the speed of the package be when it is released at the moment when the length of the spring is back to its uncompressed length?
b)Imagine you are doing this on a comet of mass 3 X 10^18 kg and radius 7X10^5 m, you indent to launch the package in such a way that it well never come back. Is the speed you calculated in part (a) enough?

A package of mass 9 kg sits on an airless asteroid of mass 8.0 x 1020 kg and radius 8.3 x 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 250 m/s. We have a large and powerful spring whose stiffness is 2.8 x 105 N/m. How much must we compress the spring? m

A package of mass 5 kg sits on an airless asteroid of mass 9.4 × 1020 kg and radius 9.0 × 105 m. We want to launch the package in such a way that it will never come back, and when it is very far from the asteroid it will be traveling with speed 170 m/s. We have a large and powerful spring whose stiffness is 2.8 × 105 N/m. How much must we compress the spring? m

A spring with a relaxed length of 25 cm and a stiffness of 13 N/m stands vertically on a table. A block of mass 73 g is attached to the top of the spring. You pull the block upward, stretching the spring until its length is now 31.7 cm, hold the block at rest for a moment, and then release it. Using a time step of 0.1 s, predict the position and momentum of the block at a time 0.2...

A relaxed spring of length 0.19 m stands vertically on the floor; its stiffness is 1270 N/m. You release a block of mass 0.5 kg from rest, with the bottom of the block 0.7 m above the floor and straight above the spring. How long is the spring when the block comes momentarily to rest on the compressed spring? m

A block with mass 0.5 kg is connected by a spring of relaxed length 0.10 m to a post at the center of a low-friction table. You pull the block straight away from the post and release it, and you observe that the period of oscillation is 0.9 s. Next you stretch the spring to a length of 0.22 m and give the block an initial speed v perpendicular to the spring, choosing v so that the motion is a...
