A force of 75 newtons is applied to an object along the x-axis while a 35-newton force is applied along the 1-axis. What is the magnitude and angle made with the x-axis of the resultant force?

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.
