A ball is kicked off a 75 m tall cliff with a horizontal velocity of 5 m/s. How long till it reaches the ground? How far will the ball land from the base of the cliff?

Let, time taken is t.

So,

( Here, us is vertical component of initial velocity )

Now, distance covered from the base of the cliff is :

Therefore, time taken and distance covered is 3.873 s and 19.365 m.

Hence, this is the required solution.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
