Alake with a surface area of 1260 acres was monitored over a period of time. during a one-month period, the inflow was 36 cfs, the outflow was 30 cfs, and a 1.6-in seepage loss was measure. during the same month, the total precipitation was 4.3 in. evaporation loss was estimated as 6.0 in. estimate the storage change for this lake during the month

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.
