Question

2017 AP PHYSICS 1 FREE-RESPONSE QUESTIONS In another experiment, teams I and 2 use tables and low-friction slides with the same height. However, the two slides have different shapes, as shown below Block I Block 2 Table 1 Table 2 Team 1 Team 2 (b) Both blocks are released from rest at the top of their respective slides at the same time Which block, if either, lands farther from its respective table? -Block 1 Briefly explain your reasoning without manipulating equations. Which block, if either, hits the floor first? i. -Block 2 The two blocks land the same distance from their respective tables. ii. Block i -Block 2 -_The two blocks hit the floor at the same time. Briefly explain your reasoning without manipulating equations.

Answer 1

(B)

(1)

both blocks are at same hight so both have same potential energy. And surface are low friction or negligible friction. So when both blocks will come on table than they will get same kinetic energy or same velocity.

So both blocks will land at same distance from from tables.

(2)

Second block cover more path than first block. So first block will hit ground first.
