1. Starting from your house, you walk 75 m east to a store, turn around, and then slowly walk 30 m west to a guava tree. It took you 32 s from house to store and 48 s from store to guava tree. a. What is your average velocity and average speed for the entire trip? b. What is your average velocity and average speed from the store to the guava tree? 2. An object's position as a function of time is x(t) = 9m + 1.5 m/s t- 3 m/s' ti. a. Calculate the object's position, velocity, and acceleration at t = 6.2 5. At this point in time, is the object to the left or to the right of the origin? is it moving towards the left or towards the right? is the object speeding up or slowing down? b. What is the maximum positive displacement reached
