Unformatted text preview: t 2 feet. (a) (6 points) What is the initial velocity of the ball? 1 (b) (7 points) What is the maximum height reached by the ball? (c) (7 points) Is the acceleration of the ball constant or not? Justify your answer. 4. (20 points) Legend has it the great pyramid of Giza was constructed in 20 years. Its base is square with sidelength 230 metres and its height is 150 metres. Assuming that slaves who constructed the pyramid increased the volume of the pyramid at a constant rate over the twenty year construction period, how quickly was the height increasing when the pyramid was 75 metres tall? State your answer in metres per year. 5. (20 points) Recall 180 & = & is the conversion from degrees to radian. Use linear approximation to estimate sin 35 & . Hint: You know sin 30 & already, & will feature in your expression. 2...
