Dhalia heads out for a bike ride. She accelerates from rest up to 3.0m/s over the span of 2.0s. Then she maintains a constant speed for 4.0s. Then, suspecting that she may have forgotten her phone at home, she slams the brakes and comes to rest over the span of 1.0s. She spends 5.0s checking her pockets while at rest, but comes up empty handed. (You may assume constant acceleration for each part of this motion.) (a) Use the graphs below to qualitatively plot Dhalia's position, velocity, and acceleration throughout the trip. (You will make things quantitative in the parts that follow.) (b) Dhalia's motion can be broken into four parts. Completely fill out the table below in order to keep track of her position, velocity, and acceleration throughout the motion. (Suggestion: start by entering what you know into the first column. Whenever you run into an empty cell, search for a kinematic equation where the only unknown corresponds to that empty cell. Then solve for that unknown!) Part #1 Part #2 Part #3 Part #4 At (c) How much time elapsed between the beginning and the end of this motion? (d) What was Dhalia's average speed during this motion
