(5%) Problem 4: A boat leaves the dock at t = 0.00 s and, starting from rest, maintains a constant acceleration of (0.314 m/s )i relative to the water. Due to currents, however, the water itself is moving with a velocity of (0.399 m/s)i + (1.5 m's)j * 50% Part (a) How fast is the boat moving, in m's, at t = 4.15 s?

Use vx = Vox tax? with vox = 0 to calculate the former. Speed is the magnitude of velocity. 4 50% Part (b) How far, in meters, is the boat from the dock at t = 4.15 s
