Question
Two masses, m and M, are released from rest at a height H above the ground. Mass m slides down a curved surface while M slides down an incline as shown. Both surfaces are frictionless and M > m. Which of the following statements is true? The time it takes for m to reach the end of the surface is longer because the path it takes is longer. The time it takes is the same since both masses are released from the same height. The time it takes for M to reach the end of the incline is less because its horizontal acceleration is larger. The time it takes for m to reach the end of the surface is shorter because it has a larger acceleration initially and therefore builds speed more quickly. The time it takes is the same since both masses have the same displacement. The time it takes is the same because both masses have the same speed at the end. The times cannot be compared without knowing the masses of the blocks. More than one statement above is correct None of the above statements is correct.
Explanation / Answer
The time it takes for m to reach the end of the surface is longer because the path it takes is longer
If path covered is longer than it would take long time
