Question

from the top of a tower ,a ball is droped to fall freely under gravity and at the same time another ball is thrown up with a velocity of 50m/s. plot the position time graph for the notion of two balls during time interval t=0sec to t=5sec​

Answer 1

Answer:  om the top of a tower, a ball is dropped to fall freely under gravity and at thesame time, another ball is thrown up with a velocity of 50 m/s. Plot the position-timegraph for the motion of the two balls during the time interval t-otot Ss. Take g 10m/s²​

Using S = ut + (1/2)gt²

Taking above from the throwing position as +ve

and below that - ve
