Question

On each bonce, a ball rises to 4/5 of its previous height. To what height will it rise after the third bounce, if dropped from height of 250 cm?

Answer 1

Answer:

128 cm

Step-by-step explanation:

After the first bounce

height = $\frac{4}{5}$ × 250 = 4 × 50 = 200 cm

After the second bounce

height = $\frac{4}{5}$ × 200 = 4 × 40 = 160 cm

After the third bounce

height = $\frac{4}{5}$ × 160 = 4 × 32 = 128 cm
