You stand on the top of a tall building and throw a baseball directly downwards. When the baseball leaves your hand, it has a speed of 6 m/s. (Assume there is no air resistance for this problem) a. Four seconds after you throw it, what is the acceleration of the baseball? Show your work and explain your steps. b. Four seconds after you throw it, what is the velocity of the baseball? Show your work and explain your steps.

I am needing assistance with this question in its entirety ***Please type your answer or write in print, because I have had great difficulty with understanding most handwritten assistance done in cursive or mixed print/cursive.

The class I'm taking is physics for scientists and engineers! *** I just need help with parts D,E and F *** I am completely stuck. Need help. I have attached the problem. Please view  attachment before answering. Thank you!

10. A plane flying at 245 m/s [E270S] takes 36 seconds to change its velocity to 245 m/s [S270E]. a) Solve for the change in velocity of the plane algebraically. b) What was the average acceleration of the plane over this time interval? c) Explain why the speed of the plane changed and yet the plane accelerated. Please labeled sketches with events as well as GRASS and explanations to show your work. Please label triangle sides. Remember to have the magnitude rounded to a reasonable number of sig figs, the unit and the direction (if needed) in your answers.

In this section, you will use your graphs to figure out key concepts. 1.Describe the motion of the ball you picked. 2. Does the ball you collected data for have a constant acceleration? Explain your reasoning. 3. According to your data, what is the acceleration of the ball you collected data for? Explain how you found your answer.
