D1 & D2
dx=25cos30 = 21.65 w+22.98 E = 1.33 E dy=26sin30+30sin40= 12.5 N+19.28 N = 31.78 N
c^2=a^2+b^2 C=31.8 m
tan= 1.33/31.78 =2.41 therefore, 31.8 m [N 2.4 E]
D1 & D3
dx=25cos60W+35cos65W =27.3 W Dy=25sin60N+35sin65[s]=10.07 S
C2=27.32+10.072= 29.1 m
Tan= 27.3/10.07 =69.75...
Use the component method to add the following displacement vectors.
D1= 25 m [N 30 W], D2= 30 m [N 40 E], D3= 35 m [S 25 W]
I know all of the equations for vx, vy and the five equations. I also know sin, cos, tan and velocity, displacement...
Within 4 sec of liftoff, a spacecraft that is uniformly accelerating straight upward from rest reaches an altitude of 450 m [up]. What is the spacecraft's acceleration?
The five key equations, plus the velocity, speed, and acceleration equations...
