Prob # 4: A ball is thrown from a height of 10 feet at 45° from the vertical with an initial speed of 40 ft/sec. Neglecting resistance and assuming the gravitational acceleration g=32 ft/see?, determine: a. Where is the ball after 2 seconds? b. What is the velocity of the ball at 2 seconds, and which direction (up or down) the ball is going? c. How high does the ball go?
