Compute all parts of given problem:
Problem: An object initially moving at 12 m/s accelerates uniformly to 33 m/s in 16 s. It continues to move at this speed for 15 s and finally comes to rest with uniform acceleration in 25 s.
Part A: Calculate the acceleration in the first 16 s?
Part B: Calculate the total distance moved?
Part C: Calculate the acceleration in the last 10 s?
Part D: Calculate the average speed in the first 30 s?
Please show me how work it out above problem.
