Question

A ball is thrown up with a velocity of 20 m/s. Construct acceleration-time graph and displacement-time graph?​

Answer 1

Answer:

Let upwards motion be +ve,

Velocity at t=0 is =20m/s

It becomes zero at,

t=

a

v

=

10

20

=2s

And then after t=2s

It comes back with a negative velocity (i.e downwards)

And comes to its initial speed ∣v∣=20m/s at t=4s
