A body is dropped from certain height and another body is dropped from same height after 2 secs. What will be the separation between two bodies 4 second after the dropping of second body.

Question

Arun · Answer

You can use Newton's second equation of motion here.
The first ball has traveled for 6 seconds under gravity with acceleration g and initial velocity=0.
The second ball has traveled for 4 seconds under gravity with acceleration g and initial velocity=0.
Distance between the 2 balls at the end of 6 seconds after the first ball is dropped = 1/2*9.8(36-16)
= 98m

Stuti · Answer

98 meters is right ans H1=1/2×9.8×6×6 H1=176.4 Now,H2=1/2×9.8×4×4 H2=78.4 Thus,the seperation between two bodies are H=H1-H2 H=178.4-78.4 H=98 meters
