Question

Chapter- 2. Kinematics in One-Dimension I. A car is traveling at 18. 5 m/s, and the driver notices that a traffic light just turned red. After the reaction time of the driver, 0.330 s later, the driver applies the brakes, and the car decelerates at 5.00 m/s2. Find the total stopping distance of the car, as measured from the point where the driver first sees the red light. (Hint: this distance is the sum of the two distances; one traveled during reaction time, and the other the braking distance). Chapter-3. Kinematics in Two-Dimensions 2. A shell is fired with a horizontal velocity in the positive x direction from the top of an 05-m high cliff. The shell strikes the ground R= 1365 m fromn the base of the cliff, as shown. The drawing is not to scale. What is the speed V of the shell as it hits the ground? a) 124 m/s ) 298 m/s (c) 310 m/s (d) 420 m/s (e) 530 m/s 95m
