A force F with arrow is applied to a 1.9-kg radio-controlled model car parallel to the x-axis as it moves along a straight track. The x-component of the force varies with the x-coordinate of the car as shown below. The model car is initially at rest at x = 0. Use the work-energy theorem to find the speed of the car at the following locations. (a) x = 3.0 m m/s (b) x = 4.0 m m/s (c) x = 6.0 m m/s

A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond
A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the 2-component of the force she applies varies with the 2-coordinate of the sled as shown in figure (Figure 1). Suppose the sled is initially at rest at x = 0. You can ignore friction between the sled and the surface of the pond. For related problemsolving tips...

A girl operates a radio-controlled model car in a vacant parking lot. The girl’s position is at the origin of the xy coordinate axes, and the surface of the parking lot lies in the xy plane. She drives the car in a straight line so that the x coordinate is defined by the relation x(t) = 0.5t3 - 3t2 + 3t + 2 where x and t are expressed in meters and seconds, respectively. Determine when the velocity is 0...
