#

The horizontal component of the V is constant as there is no acceleration

#

But in the vertical component it is changing

#

Due to G

#

Yea

#

Use the vertical one first

#

To get initial vertical velocity

#

v²=2g*(2.5)

#

v=Vcos60

#

U will get v

#

U can calculate the x

#

Which is 2v²sin.cos/g

#

That will be your answer

#

@torpid drum

#

The water jet question?

#

@torpid drum

#

U need to do the same thing here

#

As i told you

#

Take the water as a particle

#

No need for mass

#

Acc for both the particles are same

#

Forces may not be

#

Mass does matter

#

When u will study gravitation u will learn

#

But the mass of earth is so large that the acc due to the body will be really less

#

F=G(m1m2)/r²

#

The main thing u need to understand is

#

Kinematics and dynamics are whole different things

#

They are only related due to one eqn

#

That is F=Ma

#

Mass*acceleration

#

Yes

#

Force and acceleration are different things

#

By mass*

#

Not weight

#

Yes

#

On earth acc is g

#

Ye u right

Nice
