The more detailed solving process, the better. And hope you can make clear handwriting. Thank you

A jet lands on a runway. Between the time the jet touches the ground (t 0) and when it comes to rest, the jet has a velocity given by v(t)-75.0m-3.0%. ť. (a) What is the instantaneous acceleration of the jet at t -2.0 s? (b) What is the average acceleration of the jet between time it touches the ground and when it comes to rest?

A helicopter leaves the ground and travels straight upward with a height given by x(t) 5.0 . t2 . exp (-2as), where exp(y) ey ls the exponential function . (a) Determine the instantaneous velocity of the helicopter at t 0.0 s and t 3.0 s. (b) Determine the average velocity of the helicopter between t 0.0 s and t - 3.0 s. (c) Determine the maximum height the helicopter reaches. 2.0 S

Explain why the average velocity found in Example 1 is larger than the instantaneous velocity found in Example 2. (Hint: Sketch the graph of velocity as a function of time. Is the function increasing or decreasing? What does that tell you about how the velocities at the beginning and end of the time interval compare with the average velocity during that time interval?)...
