The velocity at the highest point is zero as the ball momentarily halts there before starting its downward movement. Answer- The above question is from the chapter 'Kinematics'. At highest point velocity will be zero. As it moves upwards vertically its velocity reduces gradually under the influence of earths gravity working towards the opposite direction of the balls motion. its following the same direction of the acceleration due to gravity (g). During downward movement balls direction is the same as that of gravity and as a result, the ball comes down with acceleration and reaches the ground. And one important point, during the downward fall the magnitude of the velocity of the ball just before touching the ground would be the same as the magnitude of the velocity with which it was thrown upwards (v1 here). After this, the ball starts falling downwards. The object stops at maximum height due to deceleration brought by gravity. A ball is thrown vertically upward from the top of a building 96 feet tall with an initial velocity of 80 feet per second. An object 4 cm in size is placed at a distance of 25 cm from a concave mirror of focal Here its the kinetic energy of the object which is expressed as 0.5 m V^2. Given question: 1) A body thrown vertically upwards reaches the highest point of its path in 2 s. Find the initial velocity with which the ball is thrown.
