Ответ:
28.8m
Explanation:
Given parameters:
Time of fall = 2.4s
Acceleration due to gravity = 10m/s²
Unknown:
Height of cliff = ?
Solution:
To solve this problem, we use the expression:
H = ut +
gt²
u is the initial velocity
t is the time taken
g is the acceleration
t is the time
H = 0x2.4 +
x 10x2.4² = 28.8m
