a ball is thrown vertically upward brainly

Note that the acceleration can be either 9.8 m/s2 or -9.8 m/s2. After some time when the entire KE gets nullified, the ball stops. (ignoring air resistance), As the ball reaches the maximum height now it starts its free-fall towards the earth. Answer: 1) Let the initial velocity of the ball be = u. It can be proved that the time for the downward movement or the time taken by the ball to fall from the highest point and reach the ground is same as the time required for the upward movement =v1/g, Lets prove it here mathematically:(see the diagram above for downward movement), so, T = v3/g = v1/g (from equation v above) . After a certain time period t,the ball reaches a height beyond which it cant move upwards anymore and stops there i.e. (A) 10 m/s (B) 20 m/s (C) 30 m/s (D) 50 m/s User is waiting for your help. And then starts falling towards the earths surface. In a plane mirror,the angle of incidence and angle of reflection are equal. The force applied on it is again the gravity and this time its having a positive acceleration i.e. A ball is thrown vertically upward from the top of a building 96 feet tall with an initial velocity of 80 feet per second. what is its instantaneous speed at its maximum height, Mang Erning is a farmer. He uses shirts with long sleeves so that his skin won't brushes against the leaves of his plant. Velocity at a point \( h \) meter below the point of\( \mathrm{P} \) projection is t. (ii) The total time it takes to return to the surface of the earth. 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. Its value is generally taken as 9.8 m/s^2. Using 1st equation of motion, v = u + at, we get. 4. You can specify conditions of storing and accessing cookies in your browser.
