A ball is dropped from a height of 24 meters. Each time it strikes the ground it bounces back vo a height of three-fourths the distance from which it fell. Determine the total dblanct Inverted by the before it comes to rest. Show all work. 2, 6, (5x + 3),... is a given sequence showing the first three terms. Find a value of x so that ihe sequence will be
Solution
10)total distance travelled by the ball =24 +(3/4)(24+24) + (3/4)2(24+24) +..........
total distance travelled by the ball =24 +(3/4)48 + (3/4)248 +..........
total distance travelled by the ball =24 +48[(3/4) + (3/4)2 +..........]
sum of infinate geometric series is a/(1-r) when r<1.
a=3/4 , r =3/4
total distance travelled by the ball =24 +48[(3/4)/(1-(3/4))]
total distance travelled by the ball =24 +48[(3/4)/(1/4)]
total distance travelled by the ball =24 +(48*3)
total distance travelled by the ball =168m
