A car of mass 800.0 kg accelerates away from an intersection on a horizontal road. When the car speed is 39.6 km/hr (11.0 m/s), the net power which the engine supplies is 3900.0 W (in addition to the extra power required to make up for air resistance and friction). Calculate the acceleration of the car at that time.

The figure here shows a plot of potential energy U versus position x of a 0.878 kg particle that can travel only along an x axis. (Nonconservative forces are not involved.) Three values are UA-15.0J, Us - 35.0 J and Uc-45.0 J. The particle is released at x -4.50 m with an initial speed of 7.99 m/s, headed in the negative x direction. (a) If the particle can reach x -1.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (b) magnitude and (c) direction of the force on the particle as it begins to move to the left of x- 4.00 m? Suppose, instead, the particle is headed in the positive x direction when it is released at x - 4.50 m at speed 7.99 m/s.
