A water tank is being towed on an uphill road that makes 20° with the horizontal with a constant acceleration of 5 m/s2 in the direction of motion. Determine the angle the free surface of water makes with the horizontal. What would your answer be if the direction of motion were downward on the same road with the same acceleration?
Solution to 104P
We need to find the angle which the free surface of water makes with respect to horizontal when a water tank is towed uphill and downhill.
We need to draw a free body diagram to compute the angle,
