A stone is dropped from a certain height and can reach the ground
in 5s. But in its fall, the stone is stopped after, 3s of the fall for a
moment and is dropped again at once. Now the stone reaches the ground in
total time of seconds. Find the value of t?
5s
3s
t
Show answer and solution
h = [IMAGE] × 10 × 52 = 125 m
h1 = [IMAGE] × 10 × 32 = 45
80 = [IMAGE] × 10 × t2
t = 4 sec. Total time = 3 + 4 = 7 sec
