Inclined throw - motorcycle jumps from the ramp

    Inclined throw -- motorcycle jumps from the ramp

    1. The problem statement, all variables and given/known data
    The motorcycle jumps from the ramp. what is the minimum speed at the edge in order to reach the other side.

    2. Relevant equations
    Constant acceleration: V=-gt

    3. The attempt at a solution
    The time to reach height of 1.5 meters:
    [tex]V_0\sin30^0=gt \rightarrow t=\frac{V_0}{2g}[/tex]
    The horizontal distance:
    [tex]V_0\cos30^0\cdot \frac{V_0}{2g}=10[/tex]
    [tex]V_0=15.2 [m/sec]=54.7 [km/h][/tex]
    And it should be about 45 [km/h]

    Only if the motorcycle does not have a vertical velocity at the upper point. This is not true here. It will follow a parabolic path and "fall down" a bit at the end, this increases the time.

    You'll have to consider both horizontal and vertical motion together.

    First equation is wrong one.
