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.

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

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 $\stackrel{\rightharpoonup }{C}$?

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.

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?

Your roommate drops a tennis ball from a third-story balcony. It hits the sidewalk and bounces as high as the second story. Draw a complete motion diagram of the tennis ball from the time it is released until it reaches the maximum height on its bounce. Be sure to determine and show the acceleration at the lowest point.

A bowling ball rolls up an incline and then onto a smooth, level surface. Draw a complete motion diagram of the bowling ball. Don't try to find the acceleration vector at the point where the motion changes direction; that's an issue for Chapter 4.

A speed skater accelerates from rest and then keeps skating at a constant speed. Draw a complete motion diagram of the skater.
