A cameraman on a pickup truck is traveling westward at 25 km/h while he videotapes a cheetah that is moving westward 28 km/h faster than the truck. Suddenly, the cheetah stops, turns, and then run at 50 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 2.0 s. What are the (a) magnitude and (b) direction of the animal’s acceleration according to the cameraman and the...

Students in question are in the back of a 3200 kg moving truck travelling east at 50 km/h. The students intend on ramming the truck with their 2000 kg vehicle to force it to a stop. As the moving truck moves through a nice open parking lot, they travel at 80 km/h directly southwest (50 degrees south of west) and collide with the moving truck. Both vehicles become stuck together and move off as one after the collision. Treat east...
