Answer:
v = 5cos(73°)i +5sin(73°)j
Step-by-step explanation:
The components of the velocity vector are ...
horizontal (i direction): 5·cos(73°)
vertical (j direction): 5·sin(73°)
Then the velocity vector is the sum of these component vectors:
v = 5cos(73°)i +5sin(73°)j
D=a=-3? was that written correctly?
