Answer:
c 275 m
Explanation:
Given parameters:
Final velocity = 73.5m/s
Unknown:
Height of fall = ?
Solution:
Since the body is falling from rest, U = 0 or initial velocity is 0m/s. Then we use one of the kinematics equation to solve this problem.
V² = U² + 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
73.5² = 0² + (2 x 9.8 x h)
5402.25 = 19.6h
h = 275.6m
