A hot air balloon is rising vertically with a velocity of 2.0 feet per second. A very small ball is released from the hot air balloon at the instant when it is 640 feet above the ground. Use a(t)=−32 ft/sec^2 as the acceleration due to gravity. 1. How many seconds after its release will the ball strike the ground? Round the answer to the nearest two decimal places. 2. At what velocity will it hit the ground?

(1 point) A stone is thrown straight down from the edge of a roof, 950 feet above the ground, at a speed of 7 feet per second. A. Remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 4 seconds later? B. At what time does the stone hit the ground? C. What is the velocity of the stone when it hits the ground?

7. (8 points) A 6 foot-tall man is walking away from a lamp post, which is 11 feet tall. Let u represent the man's distance from the lamp post (in feet) and let y represent the length of the man's shadow (in feet), as shown in the picture below. Determine how fast the man is walking if the length of his shadow is increasing at a rate of 12 feet per second.
