Question

a body is thrown vertically upwards with initial velocity u. does the acceleration of the
body change?why?​

Answer 1

The body that is thrown vertically upward with velocity u will have final velocity v=0 at the greatest height h.

Substituting the given values in the third equation of motion, v
