2.A 2 kg object initially moving with a constant velocity is
subjected to a force of magnitude F in the direction of
motion.A graph of F as a function of time t is shown at
the right.What is the increase,if any,of the object’s
velocity during the time the force is applied?

一个2千克的物体初始做匀速运动,现收到在沿运动方向的大小为F的力的作用.F的大小关于时间t的图像如右.那么在力F的作用期间,物体的速度的增量是多少(如果有的话).
一个2kg重的物体开始呈匀速运动,此时在其运动方向施加一个大小为F的力,这个力持续了时间t,这个力与时间的曲线关系在右侧。这个物体的速度会不会增加,如果增加的话,会增加多少?
