    Problem with finding time from projectile motion problem

    This is wrong. The time it takes for the projectile to land depends only in the y direction. Therefore, your equation should reflect only the motion of the projectile in the y direction. your velocity should therefore be 65sin(37°)m/s instead of simply 65m/s as you have here. This is the...
