The ball launcher in a pinball machine has a spring that has a force constant of 1.20N/cm . the surface on which the ball moves is inclined 10.0 degrees with respect to the horizontal. If the spring is initially compressed 5cm find the launching speed of 100g ball when the plunger is released. Friction and the mass of the plunger are negligible.


The answer should be 1.68 m/s...... How i dont know!!!, and this Q is coming n Exam and im still working on it.
Thx For helping .

I can't find anything on mathsnet.net or other maths sites. I have a past paper question to do:

the curve C has equation

y=4x^2-7x+11

and the line L has equation

y=5x+k

where k is a constant. Given that L intersects C in two distinct points, show that k>2.

I'd appreciate help on understanding the question more than an answer thanks. :D

I have read that Inbreeding leads to several complications.

if so How evoultion leads to a species with complex gene pool if the species evovles thoru inbreeding?. I mean to ask how from a limited gene pool one species can develop with huge gene pool.

For example All humans might have evloved from limited set of popluation. In that case inbreeding cannot be avoided and the genepool will be also limited. But we humans have huge genepool as of now. How could we have evolved into such complex organism. Or Humans evolved simultaneously in different part of the world?

If the earth is at perihelion in January, shouldn't it combine with the effect of tilt and make the sun feel stronger in southern latitudes, compared to an equivalent northern latitude in July?
