Let the height of the highest point be h. Using third equation of motion, v - u = 2ah, we get, 2) Initial velocity of the stone (u) = 10 m/s. Its value is generally taken as 9.8 m/s^2. v32 = v22 + 2 g H = 0 + 2 g (v12/2g) = v12i.e. The velocity of the at maximum height is 0 m/s at the highest point since, when you throw a ball upward, it decelerates and stops momentarily at the highest point before it falls back to the ground. Acceleration due to gravity going up is -9.8 m/s (decelerating), which means the velocity of the object going up decreases by 9.8 m/s every second and eventually the object will momentarily stops when it reaches it maximum height before if falls back to the ground. Then ball will fall down ward with increasing speed. Acceleration- It is the rate of change of velocity. Then again it starts falling downwards vertically and this time its velocity increases gradually under the influence of gravity. the Law of reflection would still hold even off a curved surface. 8 m s - 2 Let the maximum height be h. Step 2: Formula used After some time, it returns to the thrower. So we can say thatduring the downward fall the magnitude of the velocity of the ball just before touching the ground would be same as the magnitude of the velocity with which it was thrown upwards (v1 here). We will prove it mathematically here: Here while falling vertically downward, the ball falls the same height H (here H = v12/2g, as given in equation iv). The acceleration is negative because this acceleration is directing downwards while the ball is moving upward.And because of this negative acceleration, the velocity of the ball is gradually decreasing. Let the final velocity of the stone be v. Acceleration due to gravity (a) = 10 m/s, This site is using cookies under cookie policy . length 15 cm. In other words, during upward movement, the ball is moving with retardation. Calculate (i) The maximum height to which it rises.
