A boy drops a stone from a cliff, which reaches the ground in . Calculate the height of the cliff? [Take ]
Step 1: Given data
Initial velocity of stone,
Time taken,
Acceleration due to gravity,
Height, (To be calculated)
Step 2: Calculating the height of the cliff
Applying equation of motion for the freely falling object,
[ '' is positive when a body falls downwards]
Hence, the height of the cliff is
