If $\stackrel{\rightharpoonup }{A}=3\widehat{i}-2\widehat{j}$, $\stackrel{\rightharpoonup }{B}=2\widehat{i}$, and $\stackrel{\rightharpoonup }{C}=2\stackrel{\rightharpoonup }{B}-\stackrel{\rightharpoonup }{A}$, what is $\stackrel{\rightharpoonup }{C}$?

A rubber ball bounces. We'd like to understand how the ball bounces.a. A rubber ball has been dropped and is bouncing off the floor. Draw a motion diagram of the ball during the brief time interval that it is in contact with the floor. Show 4 or 5 frames as the ball compresses, then another 4 or 5 frames as it expands. What is the direction of a during each of these parts of the motion?

The figure shows two vectors. Which choice best represents $\stackrel{\rightharpoonup }{A}-\stackrel{\rightharpoonup }{B}$?

Seen from above, Linda runs $5.0\mathrm{m}/\mathrm{s}$ 30° north of east. What is the x component of her velocity?

Draw a pictorial representation for the following problem. Do not solve the problem. What acceleration does a rocket need to reach a speed of 200 m/s at a height of 1.0 km?

Problems 49, 50, 51, and 52 show a partial motion diagram. For each:c. Draw a pictorial representation for your problem.

Problems 44, 45, 46, 47, and 48 show a motion diagram. For each of these problems, write a one or two sentence 'story' about a real object that has this motion diagram. Your stories should talk about people or objects by name and say what they are doing.

For Problems 34, 35, 36, 37, 38, 39, 40, 41, 42, and 43, draw a complete pictorial representation. Do not solve these problems or do any mathematics.A car starts from rest at a stop sign. It accelerates at 4.0 m/s² for 6.0 s, coasts for 2.0 s, and then slows at a rate of 2.5 m/s² for the next stop sign. How far apart are the stop signs?
