Inclined throw -- motorcycle jumps from the ramp
The motorcycle jumps from the ramp. what is the minimum speed at the edge in order to reach the other side.
Constant acceleration: V=-gt
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]
