Question

A point mass is projected, making an acute angle with
the horizontal. If angle between velocity v and
acceleration g is o at any time t during the motion,
then 0 is given by
(A) 0° <O< 90° (B) 0 =90°
(C)0<90°
(D) 0°<O<180°​

Answer 1

Answer:

D option is correct

Explanation:

• Since  

• g  is always in  −y  direction and maximum angle made by projectile with  

• g  is when it is launched vertical and minimum angle will be when projectile will lead to ground making  

0

angle with  

• g

• . Hence if angle made is  

• θ

• then it will be  

1. 0 < θ < 180
