A projectile is launched from the origin at an angle θo with the horizontal; the subsequent position is given by r(t).For small enough angles the distance from the origin r=|r| always increases.However,if a projectile is launched nearly straight up it rises to a highest points,and then...
Which one of the following statements is true concerning the motion of an ideal projectile launched at an angle of 45°to the horizontal? A. The acceleration vector points opposite to the velocity vector on the way up and in the same direction as the velocity vector on the way down. B....
