When an object is shot from the bottom of a long smooth inclined plane kept at an angle 60º with horizontal, it can travel a distance x 1 along the plane. But when the inclination is decreased to 30º and the same object is shot with the same velocity, it can travel x 2 distance. Then x 1 : x 2 will be:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
v 2 final = u 2 – 2 (g sin 
) x
x 1 = 
x 2 = 
= 
= 
=
