Use a(t) = -32 ft/sec^2 as the acceleration due to gravity. (neglect air resistance.) with what initial velocity must an object be thrown upward (from ground level) to reach the top of a national monument (580 feet)? (round your answer to three decimal places.) use a(t) = -32 ft/sec^2 as the acceleration due to gravity. (neglect air resistance.) a balloon, rising vertically with a velocity of 16 feet per second, releases a sandbag at the instant when the balloon is 32 feet above the ground.

(a) how many seconds after its release will the bag strike the ground? (round your answer to two decimal places.) sec

(b) at what velocity will it strike the ground? (round your answer to three decimal places.)

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
