Question

1.28. A small body is thrown at an angle to the horizontal with
the initial velocity vo. Neglecting the air drag, find:
{a) the displacement of the body as a function of time r (t);
(b) the mean velocity vector (v) averaged over the first t seconds
and over the total time of motion.

Answer 1

Answer:

As the body is under gravity of constant accelration vector g, it's velocity vector and displacement vectors are:

Answer 2

Answer:

b) the minimum value of the total acceleration wmin and the corresponding

displacement
