Question

32) A ball is dropped from a height of 1 metre. After each bounce, the height becomes half of the previous height. What is the total distance travelled when it hits the floor for the third time?
A 1.5 m B) 2m C) 2.5 m D) 3m​

Answer 1

Answer:

c. 2.5 m

Step-by-step explanation:

Short answer:

1+(1/2+1/2)+(1/4+1/4)=1+1+1/2=2½

Explanation:

After 1st drop h=1m

Then, bounces up 1/2 m and comes down so total1(1/2+1/2=1m)

Then, again it bounces up 1/4 and comes down, total2(1/4+1/4=1/2m)

So, total distance after 3rd drop=2½m

Answer 2

Answer:

C) 2.5 m

is the correct answer.

Step-by-step explanation:

After 1st drop h=1m

Then, bounces up 1/2 m and comes down so total1(1/2+1/2=1m)

Then, again it bounces up 1/4 and comes down, total2(1/4+1/4=1/2m)

So, total distance after 3rd drop=2½m
