Question

An object is thrown vertically upwards and rises to a height of 5 m and acceleration due to gravity is 10 meter per second square. Then, the velocity with which the object was thrown upward is​

Answer 1

Answer:

v*2 -u*2 =2as

therfore v=0

s=5

a=-10(Going upwards)

u=?

therefore

0*2-u*2=2*5*(-10)

_u*2= -100

therefore

-u =-10

u=10m/s
