Answer:
A
Step-by-step explanation:
You will need to break down the particles movements into horizontal and vertical components to solve this problem
VERTICAL displacement = 14 sin ( -21.1) + 11.1 sin (38.8) = 1.9153 cm
Horizontal 14 cos (-21.1) + 11.1 cos (38.8) = 21.712 cm
MAGNITUDE of displacement = sqrt ( 1.9153^2 + 21.712^2) = 21.8 cm
angle = arctan ( 1.9153 / 21.712) = ~ +5.03 degrees
