normally the unit ramp signal is defined as follows... r(t)= t, t>=0 0,otherwise so the laplace of it is given as R(s)=1/s^2
12 ft3
24 cubes 1x1x1
2 feet is as high as 24 inches
5x3x2 = 30 30cm^3
Since the heights are the same, then the longer ramp.
the ramp is 4meters long
5J because 10/2=5
The mechanical advantage is 8/2 = 4.
all depends how big you want your ramp to be and how thick your wood is etc. etc.
the mechanical advantage would be 3 because you have to do 6 divided by 2.
If it is 0.6m (long?) then how can it be 2 m high? Also, if friction is involved, this will affect the amount of force.
80%
but its the fact ima e riding the bus anyways and i want to get out at 2 and ima have to get out at 2 anyways to go to work!!
Bigger is better no mater what situation. remember don't try this at home :)
A 2 post ramp is a car lifting tool, they lift over the head so that a mechanic can repair underneath the vehicle, they can lift up to 4000kg vehicles as high as 1800mm. They cost ÕóëŠÕŠë£1250.
The ball rolling down the ramp might not have had time to reach 9.8 m/s^2. Also the coefficient of kinetic friction might have been high for the surface of the ramp.
