Q. An airplane needs to reach a velocity of 402 km/h to take off. On a 2000 m runway, what is the minimum acceleration necessary for the plane to take flight?

Q. A major leaguer hits a baseball so that it leaves the bat at a speed of 28.0 and at an angle of 34.9 above the horizontal. You can ignore air resistance.

1)At what two times is the baseball at a height of 8.00 above the point at which it left the bat?

2)Calculate the horizontal component of the baseball's velocity at each of the two times you found in part1.

3)Calculate the vertical component of the baseball's velocity at each of the two times you found in part1.

4)What is the magnitude of the baseball's velocity when it returns to the level at which it left the bat?
