a projectile is thrown with speed u into air from a point on the horizontal ground at an angle `theta` with horizontal. If the air exerts a constant horizontal resistive force on the projectill then select correct alternative(s).

A

At the farthest point, the velocity is horizontal

B

The time for ascent equals the time for descent

C

The path of the projectile may be parabolic

D

The path of the projectile may be a straight line.

Text Solution

Verified by Experts

The correct Answer is:
C, D
Here total acceleration `a=sqrt(g^(2)+a_(x)^(2))=` constant, so path may be parabolic or straight line
