Solved: A little red wagon with mass 7.00 kg moves in a
Chapter 6, Problem 6.27(choose chapter or problem)
A little red wagon with mass 7.00 kg moves in a straight line on a frictionless horizontal surface. It has an initial speed of and then is pushed 3.0 m in the direction of the initial velocity by a force with a magnitude of 10.0 N. (a) Use the workenergy theorem to calculate the wagons final speed. (b) Calculate the acceleration produced by the force. Use this acceleration in the kinematic relationships of Chapter 2 to calculate the wagons final speed. Compare this result to that calculated in part (a).
