Passage III
An elevated inclined plane makes, an angle, θ, with a floor. Points A and B on the inclined plane are 0.50 m apart. Point B is at a height H above the floor (see Figure 1).
A solid metal sphere is released from rest at Point A and travels down the inclined plane to Point B. The sphere is in free fall between Points B and C and first hits the floor at Point C, a horizontal distance X from the bottom of the inclined plane.
Figure 2 shows how X varies with 
for different H if the sphere rolls from Point A to Point B. Figure 3 shows h.ow X varies with for different H if the sphere slides from Point A to Point B.
12. Based on Figures 2 and 3, for the sphere either sliding or rolling down the inclined plane and for H = 1.5 m, as θ increases from 5° to 45°, X :
Your Answer is
Correct Answer is H
Explanation
Look at figure 2 first, when sphere rolls, H=1.5 m, when θ is from 5° to 45°, the ordinate X first increases and then decreases;
Look at figure 3, when sphere slides, H =1.5 m, when θ is from 5° to 45°, the ordinate X also first increases and then decreases
