i only need help with part b. thanks
A stone is projected with a velocity of 30m/s from a point at the foot of an inclined plane making an angle of 30* to the horizontal. The path of the projectile can be assumed to be in the vertical plane containing the line of the greatest slope of the inclined plane. If the angle of projection @ > 30*, for what values of @ will the stone strike the inclined plane:
a) horizontally (answer 49*6*)
b) at right angles (answer 70*54*)
g = 10m/s^2
