How do you find amplitude if you have the height measured. We are doing a spring lab and we are trying to find the Spring constant using Hooke's Law. We hung a spring and put a mass on it and measured how far the bottom of the mass hanger was from the table. The height was .511 m and the mass was .21 kg.

I cannot figure out how to do this problem...

The projectile from a be-be-gun which is pointed vertically up reaches a maximum height h1. The maximum height when the same gun is tilted at an angle of 53.54 degrees with respect to the horizontal is h2. What is the ratio h2/h1 ?

i do not want the answer, that will not help me, please explain how to get the answer ... the correct answer for it btw is .6468533363118013 so u can use that the check ur method.


Please help

A force of 100 Newton’s applied to a mass, produces an acceleration of 4 m/s2. Determine the force needed to give the mass an acceleration of 16 m/s2.

A pollution-sampling rocket is launched straight upward with rockets providing a constant acceleration of 12.0m/s^2 for the 1st 1000m of flight. At that pt the rocket itself is in free fall. Whats the rockets speed when the engine cut off? Whats the max altitude reached by the rocket? Whats the time taken to get the max altitude?

Completely hypothetical question. Let's all ignore the fact that tachyons are only theoretical. Furthermore, let's assume the following (believed) parameters:
1) Tachyons have an imaginary number mass.
2) Because of #1, tachyons travel faster than light.
3) Because of #2, they travel backwards through time.

If a photon and a tachyon were emitted simultaneousely towards a target, which one would get there first? Sure, the tachyon travels faster than a photon, but it also travels backwards through time. Would this time dilation affect the outcome of the race (i.e. would it cause the tachyon to reach the target before being emitted)? Furthermore, what is this answer relative to? Is the answer from the tachyon's local spacetime or the photon's.
