A cart with mass 15.0 kg moves in a straight line on a frictionless horizontal surface. Take this surface to be along the x-axis. The cart has an initial speed of 8.00 m/s and it was pushed 5.00 m in the same direction as the initial velocity by an external force with a magnitude of 20.0 N. What is the cart's final speed?
The figure shows an overhead view of a 0.0260 kg lemon half and two of the three horizontal forces that act on it as it is on a frictionless table. Force F, has a magnitude of 6.00 N and is at e, = 25.0°. Force F2
