Question

A particle is thrown up with a certain velocity and at an angel theta with horizontal draw the graph between K.E and time​

Answer 1

Explanation:

KE first decreases and then increases and is zero at maximum height as it is totally converted into potential energy

we know that time of flight required to reach the highest point is

$t = \frac{u}{g}$

let's call this time as

${t }^{1}$
