Problem

A ball is launched from the bottom of an inclined plane that makes an angle of

30^{\circ}

with the horizontal. The launch speed is

20\,\text{m/s}

at an angle of

60^{\circ}

with the horizontal. At what distance along the incline does the ball land if the incline is moving to right at speed of

2\,\text{m/s}

? (Take

g = 10\,\text{m/s}^{2}

)
