The only force acting on a 3.3 kg body as it moves along the positive x axis has an x component Fx = -4x N, where x is in meters. The velocity of the body at x = 1.4 m is 9.2 m/s. (a) What is the velocity of the body at x = 3.8 m? (b) At what positive value of x will the body have a velocity of 5.9 m/s?

A body of mass 11.0 kg is traveling at 4.3 m/s along the positive x-axis with no external force acting. At a certain instant an internal explosion occurs, splitting the body into two chunks of 5.5 kg mass each. The explosion gives the chunks an additional 16 J of kinetic energy. Neither chunk leaves the line of original motion. Determine the speed and direction of motion of each of the chunks after the explosion. larger velocity? smaller velocity?

The force in newtons acting on a kg mass is Fx=16x3-9x2+8x+14 where x is in meters. Fx is oriented in the x-direction and acts on the 12kg mass from x0=0 to xf=5m. If initially at rest and all of the work of Fx is conserved, find the velocity of the 10kg mass at xf=10m. report results in m/s =
