A ball is launched up an inclined plane with an initial speed of 10m/s. The ball leaves the plane at B traves and eventually falls onto the level ground at C. If the plane is inclined at 30 degrees and is 2m long, find:
A) The speed of the ball just before it left the inclined plane
B) The time taken by the ball to reach C
C)The total horizontal distance traveled by the ball before reaching C.

amistre64 · Answer

is it leaving the plane at 2ms?  or at some other point B?

amistre64 · Answer

if we ignore friction, and the ball is launched UP the ramp, and not AT the ramp; then can we assume that it velocity is affected only by gravity?  or is there other factors at play here?

anonymous · Answer

Yes, it is leaving point B, which is 2meters from it's original stating point.

anonymous · Answer

Nope only gravity.  No friction or air resistance.

anonymous · Answer

Yes, that's exactly how it looks in the problem.

amistre64 · Answer

$$speed=\frac{distance}{time}$$$$time=\frac{distance}{speed}=\frac 2{10}=.2 sec$$

amistre64 · Answer

i should prolly consider the initial upward component tho

anonymous · Answer

right, and doesn't gravity effect the speed?
