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.
15. If H = 2.0 m for the rolling sphere and = 50°, X will most likely be closest to which of the following?
Your Answer is
Correct Answer is B
Explanation
Put value questions. Look at figure 2, when θ is greater than 30°, the ordinate X is decreasing, so when H=2.0 m, θ=50°, the ordinate X should be less than 0.8 m;
Look at the whole The downward trend will not drop as much as 0.5, so discharge A
