A hoop rolls up a ramp inclined at an angle of 27. If the speed of the center of mass of the hoop is 3.5 m/s at the bottom of the ramp, what height will the hoop reach?
I am just not sure how to began. I am thinking i should use work-ene theorm but then i just get stuck. i can't seem to...
the problem: a plane with a mass of (3.5X10^5)kg is landing. If the speed is 27 m/s and the net braking force is (4.30X10^5) N then a) what is the speed 7.5 sec later? and b) how far has it traveled in this time?
this is how i started, because speed is distance/time i felt that it would be...
ahh i see. then for the first ball the change in v is 25.21 m/s^2 because the initial v was 0. But then for the 2nd ball the Vf is 27.53 m/s^2 but does the mean the Vi is 11 m/s? cause if i remeber correctly, units must be the same to be added or subtracted. or am i missing something?
The question is basically:
You are on top of a edge that is 32.5m high and you drop 1 ball, moments later you throw a 2nd ball at the initial speed of 11 m/s. Which ball has a greater increase in speed, or is the increase the same? and prove it with a calculation.
I started out with the x=x0...
