Question
Choose the correct options
(1) A ball is dropped from the window of a moving train on horizontal rails, the path followed by the ball as observed by the observer on the ground is parabolic path.
(2) If T be the total time of flight of a current of water and H be the maximum height attained by it from the point of projection, then H/T will be (1/4) u sin 0
(u = projection velocity and 0 = projection angle)
(3) A hunter aims his gun and fires a bullet directly at a monkey on a tree. At the instant bullet leaves the gun, monkey drops, the bullet misses to hit the monkey.
(4) If a baseball player can throw a ball at maximum distance = d over a ground, the maximum vertical height to which he can throw it, will be d
(Ball have same initial speed in each case)
Choices
Choice (4)  Response  

a.  2 and 4 

b.  1 and 2 

c.  1 and 3 

d.  1,2 and 3
