Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_264

3/264 The small 2-kg carriage is moving freely along the horizontal with a speed of 4 m/s at time \( t = 0 \). A force applied to the carriage in the direction opposite to motion produces two impulse "peaks," one after the other, as shown by the graphical plot of the readings of the instrument which measured the force. Approximate the loading by the dashed lines and determine the velocity \( v \) of the carriage for \( t = 1.5 \) s.
