10pts} If a ball is thrown straight up into the air with a velocity of 15 m/s. How many seconds will it take for the ball to reach its peak? (Assume no air friction and g = -9.81 m/s²)

Please give the most detailed answer. I need reasoning as well. Brainliest to the person who gives the best answer

Answer 1

Answer:

-81.2361 m/s

Explanation:

15 m/s                                               15 m/s

- 9.81 m/s^2= 96.2361                      - 96.2361

Answer 2

It will take for the ball to reach its peak 81.2361 m/s if a ball is thrown straight up into the air with a velocity of 15 m/s.

15 m/s                                              

- 9.81 m/s^2= 96.2361            

Which formula has been used for change in velocity?

Use the formula for change in velocity equal the acceleration times the time, considering that the only acceleration acting is that of "g" (g = 9.8 m/s^2). Consider also that at the top of the trajectory is when the velocity becomes zero and the motion changes from upwards to downwards.It takes the tennis ball approximately 0.78 seconds to reach the maximum height.

Calculate the ball's greatest height using the vertically modelling method, h = -16t2 + vt + s, where v is just the initial velocity at feet/second and s is indeed the height in feet.

Zero The ball travels upward when you throw it, but because gravity is pulling on it, its speed diminishes as it ascends.The ball begins to slow down, and during the peak of its journey, it has zero velocity.

Therefore, It will take for the ball to reach its peak 81.2361 m/s if a ball is thrown straight up into the air with a velocity of 15 m/s.

15 m/s                                              

- 9.81 m/s^2= 96.2361
