Question

A body is thrown vertically upward in air when air resistance is taken into account, the time of ascent is t1, and time of descent is t2, then which of the following is true? (A) t1 = t2 (B) t1 < t2 (C) t1 > t2 (D) t1 <> t2

When a body is thrown up, its velocity goes on decreasing. Air resistance is smaller. When a body falls down, its velocity goes on increasing. Air resistance is larger t2 increases.

Q. A body is thrown vertically upward in air when air resistance is taken into account, the time of ascent is $t_{1}$ , and time of descent is $t_{2}$ , then which of the following is true?

$t_{1} = t_{2}$

$t_{1} < t_{2}$

$t_{1} > t_{2}$

$t_{1}_{<}^{>} t_{2}$

Q. A body is thrown vertically upward in air when air resistance is taken into account, the time of ascent is t1​, and time of descent is t2​, then which of the following is true?

t1​=t2​

t1​<t2​

t1​>t2​

t1​<>​t2​
