A descent vehicle landing on the moon has a vertical velocity toward the surface of the moon of 36.5 m/s. At the same time, it has a horizontal velocity of 55.3 m/s. At what speed does the vehicle move along its descent path? Answer in units of m/s

Respuesta :

Answer:

66.26 m/s

Explanation:

Horizontal velocity, Vx = 55.3 m/s

Vertical velocity, Vy = 36.5 m/s

The value of the resultant velocity is given by the vector sum of the two velocities which are acting at 90°.

[tex]V=\sqrt{V_{x}^{2}+V_{y^{2}}}[/tex]

[tex]V=\sqrt{55.3^{2}+36.5^{2}}}[/tex]

V = 66.26 m/s

Thus, the velocity of the vehicle is 66.26 m/s along its descent path.
