So, the magnitude of the resultant displacement is 48.2 km, and its direction is 38.3° south of west.
The acceleration of the block is 4.90 m/s^2. So, the magnitude of the resultant displacement is 48
a = F / m = (mg * sin(30.0°)) / m = g * sin(30.0°) = 9.80 m/s^2 * 0.500 = 4.90 m/s^2 So, the magnitude of the resultant displacement is 48
The direction is:
The force acting on the block is:
R = √(37.5 km)^2 + (-30.3 km)^2 = 48.2 km So, the magnitude of the resultant displacement is 48
