A) are smaller for Block 1 than Block 2.
B) are larger for Block 1 than Block 2.
C) are the same for Block 1 and Block 2.
D) depend on mass and angle, so the question cannot be answered.
Correct Answer: C
Solution :
[c] Since the speeds are the same at the track ends and they both fall through a vertical distance of 1 m from the track bottom, conservation of energy shows that their speeds when they strike the floor are equal also. Assume h = 1m and v = 4.85 m/sec for both. Then : \[1/2m{{v}^{2}}+mgh=1/2m{{V}^{2}}\] (The mass will cancel, so V is the same for both blocks.)
