Answer:
The minimum speed is 7.5 m/s.
Explanation:
Given that,
Height = 2.87 m
We need to calculate the minimum speed
Using equation of motion
Where, u = minimum velocity
g = acceleration due to gravity
h = height
Put the value into the formula
Hence, The minimum speed is 7.5 m/s.
Answer:
130 cm
Explanation:
After each bounce, the mechanical energy decreases by 18%, which means the maximum height decreases by 18%. Modeling this as exponential decay:
h = 290 (1 − 0.18)ⁿ
h = 290 (0.82)ⁿ
h = 290 (0.82)⁴
h = 130
The ball reaches a height of 130 cm.
