height?What is the ball’s acceleration at this point?
有一道英文的物理题求大神讲解A 1-kg ball is thrown straight up in the air.What is thenet force acting on the ball when it reaches its maximumheight?What is the ball’s acceleration at this point?
When it reaches the summit,the net force is only gravity and no air resistance (since v=0).the instant acceleration is g.
