CINEMÁTICA (LANÇAMENTO HORIZONTAL) NA ESPCEX 2021!

Statement: On a staircase, a sphere is launched with a horizontal velocity of magnitude V0 from the end of the first step, which is of height h relative to the second step. The sphere reaches a point x on the perfectly smooth surface of the second step, which has a length D, and immediately begins to slide without rolling, also with a constant horizontal velocity V0, until it reaches the end of the second step. It then travels a height of 2h vertically and hits the ground at a distance L from the base of the second step, as shown in the drawing below. We can state that the time interval that the sphere takes, sliding without rolling, on the smooth surface of the second step is: Data: disregard air resistance and consider the magnitude of the acceleration due to gravity to be g. In this video, I present the solution to a Physics question from the ESPCEX 2021 exam. This question involves kinematics (horizontal launch).
