The kinematical graphs of a person riding her bicycle are shown below. Time is measured in second, velocity in m/s and acceleration in m/s2. Assume that she starts at x=0.       Describe the motion of the bicyclist (direction of velocity and whether the velocity is constant, increasing and decreasing) during each 1s interval from 0-4 s using the graph. Draw the position – time (x-t) graph of this motion. This is qualitative only, showing the shapes of the x-t curves in each interval and need not be drawn to scale. Draw the acceleration – time graph (a-t graph) for this motion. Draw this graph showing the values of acceleration in m/s2. What is the displacement of the bicyclist from 0-4 s. What physics principle did you use? Show your work.

A particular rabbit accelerates from rest to a speed of 11.7 m/s in 1.2 seconds. What is the rabbit's average acceleration during that time interval? (Assume the acceleration is positive in our coordinate system, and give your answer in m/s2 .)

An individual at the edge of a cliff drops a ball meanwhile another human at the base of a cliff throws a ball straight upward. When the 2 balls meet, the one thrown from the base of the cliff is descending. Sketch the y versus t graph showing the motion of the balls please.

sketch what you think the speed time graph would look like for a vehicle that begins at 10 m/hr. and remains at that speed for 10 minutes.  Label this section A.  Then the vehicle (over a five-minute interval) increases speed from 10 to 20 m/hr.  Label this section B.  Then immediately the vehicle begins to slow down.  It takes the vehicle 10 minutes to slow down from 20 m/hr. to zero.  Label this section C.   This graph would have 3 intervals.  The first interval (A) is from 0 to 10 minutes.  The second interval (B) is from 10 minutes to 15 minutes.  The third interval (C) is from 15 minutes to 25 minutes.  The x-axis needs to go from zero to 25 minutes.  The y axis needs to go from zero to 20 m/hr.  Describe the motion of the vehicle in each interval  as increasing, decreasing, constant, or at rest.

Please box both answers.

This position time graph describes an object's motion. Use it to predict the position (in m) of the object at a time of 24.0 seconds.

A boulder starting from rest rolls down a hill in a straight line, which we shall call the xx axis. A graph of its position xx as a function of time tt is shown in the figure. (Figure attached)   1) Find the distance the boulder rolled between the end of the first second and the end of the third second. Express your answer in meters to one significant figure.   2) Find the boulder’s average speed during the first second. Express your answer in meters per second to one significant figure.   3) Find the boulder’s average speed during the second second. Express your answer in meters per second to one significant figure.   4) Find the boulder’s average speed during the third second. Express your answer in meters per second to one significant figure.   5) Find the boulder’s average speed during the fourth second. Express your answer in meters per second to one significant figure.   6) Find the boulder’s average speed during the first 4 seconds. Express your answer in meters per…

Q1: A dolphin in an aquatic show jumps straight up out of the water at a velocity of 13.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known and identify its value. Then identify the unknown, and discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long is the dolphin in the air? Neglect any effects due to his size or orientation.
