A football is kicked with a speed of 18 m/s at an angle of 65° to the horizontal.
-What are the respective horizontal and vertical components of the initial velocity of the football?
A)7.6 m/s, 16 m/s
B)16 m/s, 7.6 m/s
C)8.4 m/s, 13 m/s
D)13 m/s, 8.4 m/s
E)9 m/s, 9 m/s

The horizontal component of velocity (Vx) can be found using:
Vx = Vcos(θ) = 18cos(65°) ≈ 7.6 m/s

The vertical component of velocity (Vy) can be found using:
Vy = Vsin(θ) = 18sin(65°) ≈ 16 m/s

Therefore, the correct choice is A, with the horizontal and vertical components being 7.6 m/s and 16 m/s respectively.
