Suppose that this equation models the oscillation of an undamped vertical mass-spring system with a 2kg mass (in mks units). How much does the length of the unloaded spring increase when you hang the mass from it? 1.5 Incorrect: Your answer is incorrect. mete

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.
