1.) Please use the following graph to determine: a.) The frame of reference? b.) The instantaneous velocity at t = 4 c.) The acceleration along line h d.) Is our velocity positive or negative along line h? e.) What is the position at t = 6? 3 B C 2 g h Velocity (m/s) D 0 N 3 4 5 6 Time (s)2.) Please use the following graph to determine: a.) The frame of reference b.) The Instantaneous velocity at t = 1 c.) The acceleration at t = 1 d.) The position at point F 2 B C g f A 0 h 2 3 5 6 Position (m) D E F -2 -3 Time (s)3.) Use the information you are given to determine what type of graph you are looking at, and then answer the questions that follow. Assume your units will be some combination of meters and/or seconds, and that a positive value suggests a rightward direction. a.) The velocity at t = 4 (hidden under the 'h') is 0m/s Right b.) The position at t = 8 is 1m Right c.) The position at t = 7 is 0.5m Left d.) What is the velocity at t = 6? e.) What is the position att = 3
