Valve cover.

conservation of energy says PE+KE=PE+KE so mgh1+.5mv^2=mgh2+.5mv^2 since the mass is the same for all it can be eliminated so gh1+.5v^2=gh2+.5v^2 the left side of the equation is point A and the right side is point B. so just substitute in to find the values.

US system sends one guy to jail for two years for dog fighting Another guy kills someone in a DUI accident and gets 30 days And you are calling the Canadian system a joke?

use the equation vf^2=vi^2+2gh since vi is zero we can eliminate it so vf=sqrt(2gh) vf=SQRT(2(9.81)(5.5)) vf=10.39m/s

a. f=ma divide the force by the mass to get the acceleration b. 10N because of newtons third law for every action there is an equal and opposite reaction. c. divide the 10n by the astronauts mass to get the acceleration.
