1. V = sqrt((57.2)^2 + (35.4)^2)=67.3m/s.
2. tanA = -35.4 / 57.2 = -0,6189
A = -31.75 deg.,CW.
A = -31.75 + 360 = 328 deg.,CCW.
A = 328 - 270 = 58 deg. with vertical.
A descent vehicle landing on the moon has
a vertical velocity toward the surface of the moon of 35.4 m/s. At the same time, it has a horizontal velocity of 57.2 m/s.
At what speed does the vehicle move along
its descent path?
At what angle with the vertical is its path?
