It takes you 200.0 ms for you to react and to begin applying the brakes. Once you start braking, you accelerate uniformly to rest in 2.00 seconds. a) Sketch the velocity-time and position-time graphs for your car from the moment you saw the squirrel. [East] [East] b) Briefly explain the analysis you would perform to find the total displacement of the train over the trip described. (No calculations are required).HELP me pleaseA. Answer the following questions correctly. 1. Can a displacement from one point to another be zero, yet the distance involved in moving these points be non-zero? Can the distance between two points be zero, yet the displacement from one point to the other be non-zero? Explain. Can the velocity of an object be in different direction than the acceleration? Give example. Explain how a body moves with (a) uniform motion, and (b) uniformly accelerated motion. Is it possible for a body to accelerate when its velocity is constant? Explain. 4. 5.

- While strolling downtown on a Saturday Afternoon, you stumble across an old car show. As you are walking along an alley toward a main street, you glimpse a particularly stylish Alpha Romeo pass by. Tall buildings on either side of the alley obscure your view, so you see the car only as it passes between the buildings. Thinking back to your physics class, you realize that you can calculate the cars acceleration. You estimate the width of the alleyway between the two buildings to be 4 m. The car was in view for 0.5 s. You also heard the engine rev when the car started from a red light, so you know the Alpha Romeo started from rest 2 s before you first saw it. Find the magnitude of its acceleration.Two birds begin next to each other and then fly through the air at the same elevation above level ground at 22.5 m/s. One flies northeast, and the other flies northwest. After flying for 10.5 s, what is the distance between them? Ignore the curvature of the Earth.A train leaving Albuquerque travels 293 miles, due east, to Amarillo. The train spends a couple of days at the station in Amarillo and then heads back west 107 miles where it stops in Tucumcari. Suppose the positive x direction points to the east and Albuquerque is at the origin of this axis. a. What is the total distance traveled by the train from Albuquerque to Tucumcari? b. What is the displacement of the train for the entire journey? Give both answers in appropriate SI units.
