Question 1 1. A man is walking forward inside of an airplane at a velocity of 1.5 miles per hour relative to the airplane. The airplane is travelling at a velocity of 540.0 miles per hour relative to the ground. What is the man's velocity relative to the ground?

Question 2 2. A construction worker uses a wheelbarrow to transport a 300-newton load of metal rods to the interior of a building. The perpendicular distance from the top of the wheelbarrow's handles to the wheelbarrow's front wheels is 1.1 meters. The perpendicular distance from the center of the wheelbarrow's load to the wheelbarrow's front wheels is 0.4 meters. What is the mechanical advantage that Jim obtains from the wheelbarrow?
