Complete question :
A car accident my rolls off a cliff as it leaves the cliff it has a horizontal velocity of 13 ms it hits the ground 60 m from the shoreline calculate the height of the cliff
Answer:
104.59 m
Step-by-step explanation:
Given that:
Horizontal Velocity = 13 m/s
Horizontal distance = 60 m
To obtain the height of the cliff :
We use the Relation :
S = ut + 0.5at²
t = time ; u = initial velocity ; S = height
To obtain t ;
Speed = distance / time
Horizontal distance / speed = time
Time = 60 / 13
Time = 4.62 seconds
The height of cliff :
u = 0
Hence ;
S = ut + 0.5at²
S = 0 + 0.5(9.8) * 4.62^2
S = 104.58756
Height of cliff = 104.59 m
