Session 2013/2014 16. (a) In an arithmetic progression, the sum of the first four terms is 46 and the seventh term exceeds twice of the second term by 5. Obtain the first term and the common difference for the progression. Hence, calculate the sum of the first ten even terms of the progression. A ball is dropped from a height of 2 m. Each time the ball hits the floor, it (b) 3 of its previous height. 4. bounces vertically to a height that is (i) (ii) Find the height of the ball at the tenth bounce. Find the total distance that the ball will travel before the eleventh bounce.
