1. A car is traveling along a straight highway with a speed of 64.8 kph (18 m/s) when the driver suddenly applies the brakes just before entering the curved section A-B, REDUCING its speed at a constant rate until it reaches pointB. The 100-m long curved section A-B has a constant radius of curvature r. An accelerometer mounted on the car recorded a total acceleration of 1.41 m/s^2 just before the car passes point B.B100 mA. If the car takes 8 seconds to travel from point A to point B, what is the speed of the car at point B?B. What is the radius of curvature r of section A-B? 2.

1.A spacecraft starts from rest, and makes a journey to a destination 258000 km from its starting point. It does so by accelerating at a constant rate of 11.65 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 11.65 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take? 2 hr 37 min 1 hr 51 min 6 hr 9 min 3 hr 5 min 2.
