- *THIS IS ONE SINGLE QUESTION* The graph below depicts the velocity, measured in meters per second, of a particle moving along the x-axis. The numbers given in the graph represent the area of each interval on [0,7], [7.10] and [10.12]. The particle's position is continuous on the time interval from [0,12] seconds. a. Set up an Integral expression for the total distance travelled by the particle in the first 12 seconds, then evaluate. b. set up an Integral expression for the total displacement of the particle in the first 12 seconds, then evaluate. c. find the values where the particle is change directions. determine whether each is a relative minimum or maximum in position. justify d. the initial position of the particle is 2 units to the right of the origin. find the particle's position at time t=12. candidates chart.arrow_forwardDetermine the fit functions that best represent the position vs. time graphs in the x and y directions. Determine the acceleration as the block slides down the track for a given angle. Graph the magnitude of the kinetic frictional force versus the magnitude of the normal force for one block mass and the different angles you used. How does the magnitude of the kinetic frictional force on an object depend on the normal force on the object? What role does the kinetic frictional force play as the crates go sliding down the ramp?arrow_forwardThe graph that is shown was made using a force sensor while attempting to move box of weights across a table. The sensor pulled the box , which at first did not budge. Eventually, the box started to slide. Using the graph, estimate the force of sliding friction that was acting on the box during this experiment. Just enter a number for your answer without units.arrow_forward
