## Questions physics An apple falls from a tree and hits the ground

an apple drops from a tree and hits the ground in one second. what is it's speed upon striking the ground? what is the average speed during the one second? how high above ground was it when it's first dropped? Solution: Let: P L s OA? R Lëá R Ô. Nov 19, An apple falls from a tree and hits the ground m below.

With what speed will it hit the ground? The acceleration of gravity is m/s 2. Answer in units of m/s. physic. A circus performer throws an apple toward a hoop held by a performer on a platform (see figure below). The thrower aims for the hoop and throws with a speed of 28 m/s. An apple drops from a tree and hits the ground in one second. What is its speed upon striking the ground?

What is its average speed during the one second? How high above ground was the apple when it first dropped? Answer: The speed when it strikes the ground is 10 m/s. The average speed was 5 m/s and the apple dropped from a height of 5 meters.

Question: A) Calculate The Instantaneous Speed Of An Apple Seconds After Being Dropped From Rest. (b) An Apple Drops From A Tree And Hits The Ground In Seconds.

Calculate How Far It. Feb 06, and second later hits the ground.

### If the initial displacement and velocity are both equal to zero, it boils down to.

how fst is the apple falling when it hits the ground. i think it is v = gt m/s2 Last edited by a moderator: Feb 6, The speed when it strikes the ground is 10 m/s. The average speed was 5 m/s and the apple dropped from a height of 5 meters. On a speed-versus-time graph, the speed v of a freely falling object can be plotted on the vertical axis and time t on the horizontal axis. An apple drops from a tree and hits the ground in one second. What is its speed upon striking the ground?

What is its average speed during the one second? How high above ground was the apple when it. This is the amount of time after which it will hit the ground. Taking the derivative of − x 2 is − x. (− )= − Therefore the velocity of the object when it hits the ground is m/s downwards. This is assuming at sea level with no air resistance. Hope this. An apple falls from a tree and hits the ground 5 meters below. It hits the ground with a speed of about: a.

5 m/s b. 10 m/s c. 15 m/s d. 20 m/s e. Not enough information given to estimate. Reasoning: For the apple to fall 5 m in its fall, it must be falling for about 1 second, (read pagesand chack Table ). Thus in one second, its speed increases by about 10 m/s. Feb 22, What happens when an apple drops from the tree Why?

When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.
