1. Now Little Susie and the Purple Playground Rhinoceros are racing to see who is faster. They hang a string across the hallway with tape 6.75 meters from the starting line. They countdown from five and go! a. Susie's final velocity was 11.3 m/s. What was her acceleration?

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.
