Question

A descent vehicle landing on the moon has
a vertical velocity toward the surface of the
moon of 36.8 m/s. At the same time, it has a
horizontal velocity of 52.6 m/s.
At what speed does the vehicle move along
its descent path?
Answer in units of m/s.
At what angle with the vertical is its path?
Answer in units of ◦
.

Answer 1

X = 52.6 m/s.
Y = 36.8 m/s.
Speed = sqrt(X^2+Y^2).

Tan A = Y/X = 36.8/52.6 = 0.69962
A = 34.98o CCW = 55.02o From vertical.
