Prelab Assignment Figure 2. 1 A block starts at rest on a frictionless ramp that's inclined 9 above the horizontal. Question Pre1: a) The frictionless ramp in Figure 2. 1 is inclined 20 degrees above the horizontal. A block is placed on the incline 2.0 m from the bottom of the incline. If the block starts from rest. how long does the boxtake to reach the bottom of the incline? b) What is the Speed of the block 1when it reaches the bottom of the incline? Lab 2: Motion in One Dimension - Part 2 23 c) Ifyou were able to adjust the incline angle 9 of the ramp. for what angle would the acceleration down the ramp be greatest? Explain
