Question

A descent vehicle landing on the moon has

Answer 1

The speed of the vehicle is 62.8 m/s

What is the velocity?

We have the descent vehicle landing on the moon and the following information  are available;

vertical velocity toward the surface of the moon = 29.1 m/s

horizontal velocity = 55.6 m/s

Thus the speed along the descent path = √(29.1)^2 + ( 55.6)^2

= 62.8 m/s

Now the angle is obtained from;

180° - tan-1( 55.6/29.1)

= 118 degrees
