Particle Projection

A particle is projected from a point on a horizontal plane and has an initial speed of 49√ 2m/s at an angle of 45◦ above the plane. If the particle returns to the plane, find: (i) the time of flight; (ii) the time taken to reach the highest point. Hint: You may use the formulas for the horizontal x(t) and vertical y(t) displacement of the particle: x(t) = u cos(α)t, y(t) = u sin(α)t − 1 2 gt2 , g = 10m/sec2 , where u is the initial speed and α is the initial inclination angle to the horizontal
