Hey! Please help me, I am stuck!!
A ball is dropped from a height of 10 m. It bounces to a height of 7 m and continues to bounce. Subsequent heights to which it bounces follow a geometric sequence. Find out:
a) How high it will bounce after the fourth bounce.
b)The total distance travelled after it hits the ground for the sixth time.
For a) I got 2.401 which is right.
b) Answer is meant to be 48.82 but how do you get that?
Thanks sooo much!!
