Answer:
initial velocity = 9.8m/s
final velocity = 0m/s
upward acceleration = -9.8m/s^2
now ,
using v^2 - u^2 = 2 gh
0 - 96.04 = -19.6 ×h
19.06 = 19.6 × h
h = 19.06 ÷19.6 = 0.97 meter
Answer:
4.9
Explanation:
intial velocity = 9.8
final velocity = 0
v² - u² = 2gh
(0)² - (9.8)² = 2 × -9.8 × h
- 94.06 = -19.6 × h
h = 94.06 / 19.6 = 4.9 m is the answer
