What is the velocity of the ball just before touching the ground? This is basis of curved mirrors such as concave and convex Brainly User In a plane mirror,the angle of incidence and angle of reflection are equal. In other words, during upward movement, the ball is moving with retardation. placed 20 cm away from the mirror. (Acceleration due to gravity = 10 m/s) 2) A stone is thrown down vertically from the top of a tower with initial velocity of 10 m/s. Just summing up the answer here though we have already gone through this in the section above. Calculate the velocity with which the stone strikes the ground and the height of the tower. Solution Step 1: Given Data The initial velocity of the ball u = 49 m s - 1 The final velocity of the ball v = 0 Let the acceleration due to gravity be g = 9. the Law of reflection would still hold even off a curved surface. What is its acceleration right before it hits the earth? How do these plants protect themselves from enemies? Anupam M (NIT graduate) is the founder-blogger of this site. The influence is negative because gravity is pulling downwards while the ball is trying to move upwards. Also, find the height of this highest point. And the acceleration working on the ball at this point is the acceleration due to gravity (g) and this time its considered positive i.e. It is a vector quantity as it possesses magnitude and direction. (vi), So Time for downward movement (T) = Time for upward movement ( t ) = v1/g, That means, time for downward travel = time of upward travel, So (from equation ii and vi) for a vertically thrown object the total time taken for its upward and downward movements= t + T=2v1/g . The distance s (in feet) of the ba. a negative acceleration was working on the ball. rajsri1975p85ug8 rajsri1975p85ug8 03.05.2018 Science Secondary School answered A ball is thrown vertically upwards 2 See answers Advertisement T-T jk i don't. 5. its velocity becomes zero at that height. **Those who are aware of escape velocity, you can read a post on it here: Escape Velocity. A ball is thrown vertically upward from the top of a building 96 feet tall with an initial velocity of 80 feet per second. 4. 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). At highest point velocity will be zero. Why an object thrown upwards comes down after reaching a point? A ball is thrown vertically upwards with a velocity of 49m/s calculate maximum height and time taken to reach maximum height. Universal Law of Gravitation & Derivation of Gravitational Force formula. 1. After this, the ball starts falling downwards. Now from the Law of conversation of energy, we can say this rise in PE is happening at the cost of some form of energy being transformed. Since the angles are measured from the normal, which is perpendicular to the surface, curved surfaces don't matter. 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).
