a disturbance that transfers energy from one place to another without transferring matter
O a disturbance that transfers matter
O a disturbance that transfers matter from one place to another

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.

Happiness is to senipah as 517768399 is to what?

What is "decrease in velocity" i need offering 60 !
