Where s is in feet and t is in seconds. When will Bugs hit the ground? Warm up 10/13 Bugs Bunny has been capture by Yosemite Sam and forced to “walk the plank.” Instead of waiting for Yosemite Sam to finish cutting the board from underneath him, Bugs finally decides just to jump. Bugs’ position , s, is given by Where s is in feet and t is in seconds. When will Bugs hit the ground? What is Bugs’ velocity at impact? Units? What is Bugs’ average velocity from 0 to 3 sec? Find Bugs’ acceleration as a function of time. Units?

Suppose the graph below shows the velocity of a particle moving along the x-axis Which way does the particle move first? When does the particle stop? When does the particle change direction? Graph the acceleration for 0 to 10 . d) When is the particle speeding up? f) When is the particle moving at a constant speed?
