Question 1: The image shows a visualization of velocity vs time data for Teacher Olivia's dog, Rocko, as he was running at the dog park. What is Rocko's
acceleration? Remember to include correct units! Hint: use the graphing cheat
sheet in the Rocket Story Notebook *

Work = force × a. work b. energy c. distance d. momentum

Properties seen when one one substance changes to another are known as properties

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
