3.- Un proyectil es lanzado verticalmente hacia arriba con una rapidez de 2630km/h. Calcular la rapidez que tendrá cuando haya alcanzado la mitad de su
altura máxima y la posición al cabo de 1,5s.

Ithink the answer is c but then again i'm probably wrong

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .
