Two stones are thrown up simultaneously from the edge of a cliff 240 m high with initial speed of 10 m/s and 40 m/s respectively. Which of the following graph best represents the time variation of relative position of the second stone with respect to the first? (Assume stones do not rebound after hitting the ground and neglect air resistance, take g=10 m/s2
As we discussed in
2nd equation or Position- time equation -
Displacement
Initial velocity
acceleration
time
-
For stone 1
For stone 2
After 8 second stone 1 reaches ground
therefore it will be a parabolic curve.
