a body of mass M is thrown vertically upward into the air when initial velocity v a constant force f due to a resistance act on the body opposite to the direction of the motion of the body what is the velocity of the body at the height H above the surface during ascent?

On its way up the ball actually begins to fall as soon as it leaves your hand. Its weight causes it to accelerate downward and therefore its velocity decreases until it reaches 0 m/s at the top of its motion. Then, it begins to accelerate due to gravity at -9.8 m/s2.
