Question

5.
A ball is thrown upward with a velocity u such that it travelled a height more than the height of a
building h. If t1 and t2 are the two times in which the displacement of the ball was h. Find.
a) t1 + t2
b) t1*t2
​

Answer 1

Answer:

h=21g(t1+t2)2

g2h=(t1+t2)2→(1)

2h=21gt12

t12=gh→(2)

From (1) & (2)

t12=2(t1+t2)2

t1=1.41(t1+t2)

t1=0.41t2⇒ so, t1=2.414t2
