1. 

15 m divided by 3 mins = 5 m/ min

2.

One summer day you decided to take a ride on your skateboard to the park.  As you cruise down the sidewalk, all of a sudden your front wheels of your skateboard get stuck in a crack.  Using the ideas of Newton's First Law of Motion and Inertia, explain what will happen. 

OR 

Transportation vehicles, such as cars, buses, and trucks are commonly involved in Newton's First Law of Motion.  The processes of this law are reduced through the use of seat belts and air bags within transportation vehicles.  Design (develop a diagram) a transportation vehicle with newly invented safety devices that can greatly reduce the processes of Newton's First Law of Motion.  Explain how your vehicle reduces the affects of Newton's First Law of Motion.
