Question

A ball is thrown vertically upward with some velocity. A constant air resistance acts. If the time of ascent is t1 and that of descent is t2, then
A) t1 < t2
B) t1 > t2

C) t1 = t2
D) None​

Answer 1

Answer:

yyxitxoyxoy7$+73+3+-383+392+3

Answer 2

Answer:

c)t1=t2

EXPLATION:

Since, air resistance is constant .

Time of accent is equal to time of decent.because acceletation due to gravity is constant i.e. 9.8m/s.
