Answer:
187 meters, 90.9 degrees
Explanation:
vx = -3.09 m
vy = 187 m
Use Pythagorean theorem to find the magnitude:
v² = vx² + vy²
v² = (-3.09)² + 187²
v² = 9.55 + 34969
v² = 34978.55
v = 187 meters
Use trigonometry to find the angle:
θ = atan(vy / vx)
θ = atan(187 / -3.09)
θ = -89.1°, 90.9°
Since θ is in the second quadrant, θ = 90.9°.
