Unformatted text preview: is slowing down in a straight line. b) Because the acceleration has a component pointing in the opposite direction as the velocity, the object is slowing down. Because there is also a component of the acceleration to the right, the object is turning right as it slows down. Exercise 4. Use a scale drawing as shown at the right to get ∆ v = 130 km/h at 22.6 o north of east. Since the two velocities are at right angles to each other, we can also use the Pythagorean theorem to get the size.
