Name: Lecture Section: 8amロ11am ロ3pm give y PHYS 141-written Homework #02 Due Date: 11:59pm on Wednesday, January 30, 2019 For full credit, clear, legible, and correctly-rotated pages must be submitted to the correct location. 1. (6 points) (Based on 2.31) Using this graph showing velocity of an elevator in a tall building as a function of time, calculate 25 20 15 (a) the average acceleration from t-1s to t-3s, (b) the instantaneous acceleration at t-16s, (c) the distance travelled between t-0 and t-4s, and (d) supposing the elevator was at +75m at 10 R UUZt-0 then where was it at t-20s? Time Is -10 -15 FI F2 000 FA F7
Name: 2. (6 points) Repeat Problem 2.70, but this time, you are more carefree about the egg drop. Rather than simply releasing it from your hand, you toss it straight-up at a casual speed of 1.41 m/s. In this case, where should the professor be when you release the egg? FI F2 F3 00 FA F5
Name: 3, (8 points) (Like 2.88) In a relay race, runner #1 (already in motion) must hand a baton to runner #2 (who is waiting as runner #1 completes the first part of the race). Runner #1 is moving at a constant speed v,-8.47 m/s. Runner #2 begins from rest, and has a constant acceleration of a,-2.97 m/s2 . How far away should Runner #1 be at the moment Runner #2 begins to move so that they will both be at the same place at the same time and with the same speed? For full credit, your solution MUST include expressions for xi(t) and xol(t). 888F F3 2 3 4
