Question

a ball thrown vertically upwards with the initial velocity of 1.4m/s returns in 2 sec then find the total displacement of the ball​

Answer 1

Answer:

.1 m

Explanation:

v .sq -u. sq= 2gs

v= 0 body comes to rest while going up due to gravity

u=1.4m/s

1.4*1.4=2*9.8*s

 1.96/19.6 =s

s= .1 m

but the ball comes back after going up so displace ment=0
