Q. In a performance test, each of two cars takes 9.0 s to accelerate from rest to 27 m/s. Car A has a mass of 1400 kg, and car B has a mass of 1900 kg. Find the net average force that acts on each car during the test.

Q. A plane leaves the airport in Galisto and flies 135 km 68 degrees east of north and then changes direction to fly 219 km at 48 degrees south of east, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, how far will the crew have to fly to reach the aircraft if they fly in a straight line from Galisto?
