A plane is inclined at an angle α = 30° with respect to the horizontal. A particle is projected with a speed u = 2 ms –1 , from the base of the plane, making an angle θ = 15° with respect to the plane as shown in the figure. the distance from the base, at which the particle hits the plane is close to : (Take g = 10 ms –2 ) θ = 15° α = 30° u
