Question
Three forces F1

A child applies a force parallel to the x-axis to a 6 kg sled moving along the x-axis. The force he applies varies with the x-coordinate of the sled as shown in the figure. Suppose the sled is initially at rest at x-0 You can ignore friction between the sled and the surface F, (N) Sled 6 kg F 2.5 r (m) Find the work done by the force in moving the sled from x 0 to 4m (2 Points) Find the speed of the sled at 4 m. (2 Points) Find the work done by the force in moving the sled from xe 0 to 3 m (2 Points)

    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...

    An electron is a subatomic particle (m = 9.11 x 10^-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.32 x 10^5 m/s to a final velocity of 2.56 x 10^6 m/s while traveling a distance of 0.0934 m. The electron's acceleration is due to two electric forces parallel to the x axis: F1 = 7.82 x 10^-17 N, and F2, which points in the -x direction. Find...
