A balloon is tied to a block. The mass of the block is 2kg. The tension of the string between the balloon and the block is 30N. Due to the wind, the string has an angle θ relative to the vertical direction. cosθ = 4/5 and sinθ = 3/5. Assume the acceleration of gravity is g = 10m/s2. Also assume the block is small so the force on the block from the wind can be ignored. Then the x-component and the y-component of the acceleration a of the block.
(A) 9m/s2, 2m/s2
(B) 9m/s2, 12m/s2
(C) 18m/s2, 2m/s2
(D) 18m/s2, 12m/s2
