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

CALC. A car's velocity as a function of time is given by v_x(t) = α + βt^2, where α = 3.00 m/s and β = 0.100 m/s^3. (c) Draw v_x-t and a_x-t graphs for the car's motion between t = 0 and t = 5.00 s.

A turtle crawls along a straight line, which we will call the x-axis with the positive direction to the right. The equation for the turtle's position as a function of time is x(t) = 50.0 cm + (2.00 cm/s)t − (0.0625 cm/s2)t2. (e) Sketch graphs of x versus t, υx versus t, and ax versus t, for the time interval t = 0 to t = 40 s.

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?

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.
