Compute each part of given problem:
Problem: A cameraman on a pickup truck is traveling westward at 18 km/h while he videotapes a cheetah that is moving westward 32 km/h faster than the truck. Suddenly, the cheetah stops, turns, and then runs at 45 km/h eastward, as measured by a suddenly nervous crew member who stands alongside the cheetah's path. The change in the animal's velocity takes 1.6 s. (Use east as the positive direction.)
Part A: What is its acceleration from the prespective of the cameraman?
Part B: What is its acceleration from the perspective of the nervous crew member?
Please show all work and explain your methods for above problem.
