Question

A suspect allegedly robbed a bank in the downtown. To escape, the thief took the elevator to the roof of the building. Then, the thief allegedly threw the 30-pound bag of money to a waiting accomplice on the roof of an office building across the street. You determine that the first building is 150 feet high, and the office building is 100 feet high and its base is 50 feet from the original building. The defense attorney contends that if this scenario is true, the defendant must have thrown the money bag at least 20 miles per hour. In a test, the farthest the defendant could throw the bag while standing still was 10 feet. How will you advise the prosecuting attorney?

HELLO!! tan-1(50/50)=45o==>vo=20 mph==>vox=20*cos(45o)=14.14 mph=voy range=50/14.14=3.54 s==>y=-voy*t+1/2*ay*t2= -14.14*3.54+1/2*32.17*3.542˜151 feet below it will not reach the top of the building, therefore drop the charge
