Answer:
28.73 m from the base of the cliff collide happen
Explanation:
Equation for ball dropped from 50 cliff is reaches distance x in t seconds isi given by
stone is thrown up from the bottom with speed u=24 m/s . it reaches distance y when stone collide with ball.(g is negative here)
we know that total distance traveled by ball and stone is 50 m
adding equation 1 and 2, we get time t
substitute this time in equation 2, we can get the required distance where they collide
28.73 m from the base of the cliff collide happen
