Question

10. From the top of a tower, a ball is dropped to fall freely under
gravity and at the same time, another ball is thrown up with
a velocity of 50 m s-1. Plot the position-time graph for the
motion of the two balls during the time interval t=0 to
t=5 s. Take g = 10 m s-2​

Answer 1

Answer:

graph enclosed

Explanation:

From 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
