You purchase a used car. After handing over the cash, you drive it away from the lot, starting at rest and accelerating at 19.8 m/s2. After 16.9 s, the engine breaks down and it decelerates at 5.9 m/s2 until coming to a stop. How far were you able to drive the car? (Please answer down to the fourth decimal place- i.e 10.3456)

Solved in 2 steps with 2 images
- A rocket begins at rest in outer space. Its thrusters ignite and it accelerates at 7 m/s2 for 41 s. After that, the thrusters shut off and the rocket coasts for an additional 84 s. How far does the rocket travel during both of these time periods combined, in m? (Please answer to the fourth decimal place - i.e 14.3225)You are testing a jet back pack on a dummy. You start it rising with an upward acceleration of 3 m/sec/sec. after 9 seconds the jetpack fails (upward acceleration stops, gravity takes over). How fast is the dummy moving when it hits the ground?A burst water pipe in the city means you have to drive at a steady 12 km/h. Once past this obstacle, you speed up to 52 km/h in 10 s. You reach the freeway and, with the same acceleration, speed up for another 10 s to reach a higher speed. What is this final speed in km/h to one decimal place?
- A jet plane comes in for a landing with a speed of 120 m/s. The length of the runway is 500 m. From the instant the plane touches the runway, what is the magnitude of the acceleration needed to stop within the runway? Write your answer in terms of m/s2.Help with this question: I get 622.8 m but hw submission site says it is wrong. A space vehicle accelerates uniformly from 65.0 m/s to 162 m/s in 10.0 s. The space vehicle moves in a straight line (in one dimension). How far did the vehicle move between 1.00 s and 7.00 s?A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000 km. Suppose it accelerates at 20.0 m/s2 for the first 15.0 min. of the trip, then travels at constant speed until the last 15.0 min. when it accelerates at –20 m/s2, just coming to rest as it reaches the moon. (a) What is the maximum speed attained? (b) What fraction of the total distance is traveled at constant speed? (c) What total time is required for the trip?
- A car is traveling at a steady 81 km/h in a 50 km/h zone. A police motorcycle takes off at the instant the car passes it, accelerating at a steady 8.4 m/s2 . How much time elapses before the motorcycle is moving as fast as the car?As you ride a bicycle on the sidewalk with a speed of 5.01 m/s, a ball suddenly rolls out in front of you. You hit the brakes and come to rest in 2.0090 m. How much time did it take you to come to a complete stop?There is a 1500 mile race course. The max forward acceleration is 4 m/s2 and the max backward acceleration is 6 m/s2. I start at 600 m and must go to the 800 m mark (I must travel 200 m). What is an equation for the fastest time that I could get to 800 m? What is the position, time, and velocity of my vehicle?
- A 2 kg ball is thrown off a 73 m high cliff with a speed of 4 m/s. How fast (in m/s) is the ball going when it hits the ground? Use g = 9.8 m/s2.Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.41 m, and observe that it hits the floor 0.421 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be? 1 43.5 m/s^2 2 43.5 m/s^2 3 13.6 m/s^2 4 20.4 m/s^2A car moves in a straight line with constant acceleration. Starting from rest at t=0 it travels 8m in 4s. What is the speed of the car at t=4s? I got 2m/s but I'm not sure that's right, I would love a step by step.
