1. Suppose that you drive the 13.8 km from your university to home in 22.9 min. Calculate your average speed in kilometers per hour (km/h)and write it the box below (Hint: Average speed is distance traveled divided by time of travel.) Input your answer in km/h using 3 significant figures.

2. Suppose that the net external force exerted on a object is 7.09 N. The mass of the object is 1.54 kg. What is its acceleration? Input your answer in m/s² using 3 sinificant figures.

3. Suppose a 6.20-kg object is moving at 2.01 m/s. What is its kinetic energy? Input your answer in J using 3 sinificant figures.
