Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A sees and reacts very unwisely to the police car P. Car A is traveling at VA = 125 km/h as it passes P, but over the next 5.2 seconds, the car uniformly accelerates to 147 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.1 m/s² until a speed of 175 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. A Answer: s= i VA P m

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car Pobserves this speed via radar. The driver of
car A sees and reacts very unwisely to the police car P. Car A is traveling at VA = 125 km/h as it passes P, but over the next 5.2 seconds,
the car uniformly accelerates to 147 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins
to accelerate at the constant rate of 4.1 m/s² until a speed of 175 km/h is achieved, and that speed is then maintained. Determine the

Train A is traveling at a constant speed VA = 35 mi/hr while car B travels in a straight line along the road as shown at a constant speed VB. A conductor C in the train begins to walk to the rear of the train car at a constant speed of VC/A = 4 ft/sec relative to the train. If the conductor perceives car B to move directly westward at VB/C = 15 ft/sec, how fast is the car traveling? B UB | N x C
A helicopter starts from rest at point A and travels along the straight-line path with a constant acceleration a. If the speed v = 32 m/s when the altitude of the helicopter is h = 38 m, determine the values of r, r, 0, and 0 as measured by the tracking device at O. At this instant, 0 = 43°, and the distance d = 182 m. Neglect the small height of the tracking device above the ground. Answers: !!! = = X = i i i i ע Th m/s m/s² rad/s rad/s² A

Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 8 ft/s2 . It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 15 ft/s2.Determine the minimum distance d between the cars so as to avoid a collision.
