Acceleration Problems 1. Rob is really bored one Saturday night and goes outside to study the nocturnal habits of mice in the
hayfield. He sees a mouse sniffing along at 0.1 m/s, but it hears and starts to scurry for safety. In just 3.7
s it accelerates to 0.9 m/s. Find its acceleration.

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^.

Which system of units is used by only a small number of countries in the world, including the u.s.

Adistance-time graph indicates than an object moves 100 m in 4 s and then remains at rest for 6 s. what is the average speed of the object?
