The particle P starts from rest at point A at time t = 0 and changes its speed thereafter at a constant rate of 1.7g as it follows the horizontal path shown. Determine the magnitude and direction of its total acceleration at times t = 0.79 s and t = 1.45 s. State your directions relative to the x-axis shown (CCW positive) and choose the angle with the smallest magnitude. A B -3.17 m- 3.96 m c Answers: At t = 0.79 s, a = m/s?, e = i 47.523 249.4586 At t = 1.45 s, a = 16.677 m/s?, e = 180
