Kinematics Practice Problem 1 A particle moving along the x -axis has its position described by the function: x =2 t 2 - t +1 where t is in seconds, and x measured in meters. Find: a) the velocity of the particle as a function of time v(t) b) the acceleration as a function of time a(t) c) Is this a motion at constant acceleration? Explain. d) Make a graph for x ( t ), v ( t ) and a ( t ) for any t 0.

Unformatted text preview: b) the acceleration as a function of time a(t) c) Is this a motion at constant acceleration? Explain. d) Make a graph for x ( t ),v ( t ) and a ( t ) for any t ≥ 0. e) Describe the motion. What can it represent? Problem 3 (extra practice) Two cars are moving at 54 km/hr, one behind the other, on a road in Wasatch County. A deer jumps in front of the front car, and the driver slams on the brakes and stops. What is the minimum initial distance between the rear of the front car and the front of the second car such that the second car stops before colliding with the front car? For this problem, you can assume that the acceleration is identical for both cars and the driver of the second car begins braking 0.3 seconds after the front car brakes....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
