If Alvin Jumps off a Cliff into a Lake, How High is the Cliff?
A) 14 m
B) 38 m
C) 77 m
D) 27 m The height of the cliff is 38 meters.
Calculating the Height of the Cliff
Given:
Time (t) = 2.8 seconds
Acceleration due to gravity (g) = 9.8 m/s^2
Plugging in the values:
h = (1/2)(9.8)(2.8)^2
Calculating:
h = (1/2)(9.8)(7.84)
h = 38 meters
Therefore, the height of the cliff is 38 meters.
