The Physics of Point Particles
A student walks around in front of a motion detector that records her velocity at1-second intervals for 36 seconds. She stores the data in her graphing calculator anduses it to generate the time-velocity graph shown in Figure 3.25. Describe her motionas a function of time by reading the velocity graph. When is her speed a maximum?
High-speed motion pictures (3500 frames/second) of a
jumping 230 μg flea yielded the data to plot the flea's
acceleration as a function of time as shown in the figure (
Figure 1). (See "The Flying Leap of the Flea," by M.
Rothschild et al. in the November 1973 Scientific
American.) This flea was about 2 mm long and jumped at
a nearly vertical takeoff angle. Use the measurements
shown on the graph to answer the questions.

- A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a sketch like the figures in Section 1.2 of your textbook, marking dots for the position along the road every minute.arrow_forwardA car starts from rest and accelerates at a constant 10 m/s2 during aquarter-mile (402 m) race.

- George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his velocity in meters per second? Also, is the acceleration due to gravity negative or positive or it depends? I'm really confused. Please help and explain in an easy to understand.arrow_forwardWhen jumping, a flea accelerates at an astounding 1,000 m/s2 , but over only the very short distance of 0.5 mm. If a flea jumps straight up, and if air resistance is neglected (a rather poor approximation in this situation), how high does the flea go (write your answer in centimeters)? Acceleration due to gravity g= 9.8 m/s2.arrow_forwardCan you set up equations with variables for the two cases described? An example of a situation that I might be able to use an equation with a single unknown would be, suppose I live in a town 100 miles away from my office. How long will it take me to reach my office if I am driving at 75 mph. Time will be unknown, and I am assuming I am driving at a constant speed, so I will apply the following linear equation, Speed = Time Distance → Time = Speed Distance = 1.33hours = 1 hour 20 minutes. Now I'm in the same position as before, but now there are traffic jams, or maybe roadwork, so the speed is not constant, (it varies with time) so in this case speed(time) = time distance → time = speed(time) Distance will therefore fail in this case. In the first case, in the linear case, we can assume that the speed will be constant and independent of other variables, time, which makes the linear method useful in this situation. On the other hand, in our second example, speed is a function of…arrow_forward

The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative.
