An elevator in a high-rise building goes up and down at the same speed. Starting at the ground floor, Rafael and Monica ride up five floors, a vertical rise of 20 m. The elevator stops for 10 s as Monica gets off. Rafael then goes back down two floors. Rafael’s entire trip takes 24 s. Taking the origin to be at the ground floor, draw position-versus-time and velocityversus- time graphs for Rafael’s trip.

You are observing the poles along the side of the road. You have already stopped and measured the distance between adjacent poles as 33.1 m. You are now driving again and have activated your smartphone stopwatch. You start the stopwatch at t = 0 as you pass pole #1. At pole #2, the stopwatch reads 11.8 s. At pole #3, the stopwatch reads 30.7 s. Your friend tells you that he was pressing the brake and slowing down the car uniformly during the entire time interval from pole #1 to pole #3. (Assume you are driving in the positive direction when t = 0.) (a) What was the acceleration (in m/s²) of the car between poles #1 and #3? (Indicate the direction with the sign of your answer.) m/s² (b) What was the velocity (in m/s) of the car at pole #1? (Indicate the direction with the sign of your answer.) m/s (c) If the motion of the car continues as described, what is the number of the last pole passed before the car comes to rest?

Bob is cruising leisurely on his bike at 2.4 m/s when Jim passes him, traveling at a constant 10.2 m/s. Bob immediately begins accelerating at 2.2 m/s2 until he reaches his maximum velocity of 13.5 m/s. He continues cruising at that speed until he catches Jim. How long did it take him to catch up to Jim? (Assume the clock started at the instant he began to accelerate.) t = How far did he have to go to catch up to Jim? Ax =
One afternoon, a student was going home after attending a calculus class. For this reason, the student orders an online motorcycle taxi through the application. At the time of ordering, the online motorcycle taxi is in the position s = 2t² + 2t+4, where t is in units of time and s is in meters. a. Determine the average speed of the online motorcycle taxi at intervals of 3 minutes to 5 minutes. b. Determine the time when the instantaneous speed of the online motorcycle taxi is exactly the same as the average speed. NEED IN RUSH THANKS
The images of trees come from a catalog advertising fast-growing trees. If we mark the position of the top of the tree in the successive years, as shown in the graph in the figure, we obtain a motion diagram much like ones we have seen for other kinds of motion. The motion isn’t steady, of course. In some months the tree grows rapidly; in other months, quite slowly. We can see, though, that the average speed of growth is fairly constant for the first few years. At the end of year 3, a rope is tied to the very top of the tree to steady it. This rope is staked into the ground 15 feet away from the tree. What angle does the rope make with the ground?A. 63° B. 60°C. 30° D. 27°
