In the shown figure, a projectile is launched with speed 20√2 m/s and strikes the incline of angle 37°. Find the time of flight of the projectile along the inclined plane.

Question

G1 Physics · Accepted Answer

With uₓ = 20 m/s and uᵧ = 20 m/s in the shown directions, the vertical drop to the incline gives (5t²-20t)/(20t) = tan37° = 3 4 \frac{3}{4} 4 3 ​ , yielding t = 7 s.
