sammy [17]

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°.

V=\sqrt{V_{x}^{2}+V_{y^{2}}}

V=\sqrt{55.3^{2}+36.5^{2}}}

V = 66.26 m/s

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