1. A racing car accelerated uniformly from 44 m/s to 66 m/s in an 11 second period. Determine its acceleration. 2. A racing car car uniformly from 66 m/s in an 11 seconds period. Determine its acceleration.

3. A train moving 15 m/s is uniformly accelerated to
17 m/s over 12 seconds period. Finds its acceleration.

Ways that industry and agriculture use physical properties to separate substances

What property of an object determines its inertia?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
