The drag racer P starts from rest at the start line S and then accelerates along the track. When it has traveled 112 m, its speed is 50 m/s and it is accelerating forward at 10.0 m/s2. For that instant, determine the values of r and θ relative to axes fixed to an observer o in the grandstand G as shown. 歇一 36 m 0
Practice Problems 12-12. Determine the total time required for a car to travel 1km along a straight road if it starts from rest (position 1), reaches a maximum speed at some intermediate point (position 2) and then stops at the end of the road (position 3). The car accelerates at 1.5m/s2 and decelerates at 2m/s. Hint: Draw a straight line with three positions marked on it. Write kinematics equations corresponding to positions 1-2 and 2-3, and solve the resulting equations...
