Question

a ball is thrown upwards with 20m/s what dist will be travelled in 3 s​

Answer 1

initial velocity is =20m/s

final velocity is =0m/s

time=3sec

a=V-U/T

a=0-20/3

a=-20/3

2as=v square - u square

2*-20/3*s=(0)square -(20)square

-40/3s=0-400

-40s=-400*3

40s=1200

s=1200/40

s=30metres
