1. A study was done to find if different tire treads affect the braking distance of a car. I: tire treads D: braking distance С: car 2. The time it takes to run a mile depends on the person's running speed. I: D: С: 3. The height of bean plants depends on the amount of water they receive. I: D: C: 4. The higher the temperature of the air in the oven, the faster(time) a cake will bake. I: D: С: 5. Lemon trees receiving the most water produced the most lemons (fruits). I: D: С: 6. Students measured the temperature of the water at different depths in Lake Skywalker and found that the temperature varied. I: D: С:

Using what's given below, answer the following parts for practice:  Ansdrew needs to get produce from the store, which is a distance d=2.87 km east of his condo. Andrew rides his bicycle to the store at a constant speed of v1= 6.19 m/s, and rides back to his condoat the slower speed of v2=2.22 m/s. The figure below is not drawn to scale.  Part A: How long, in seconds, does it take for Andrew to reach the store? And how long in both seconds and minutes does the whole trip take?  Part B: What total distance, in kilometers, was traveled by Andrew during the whole trip?  Part C: What is the magnitude, in kilometers, of Andrew's displacement for the entire trip and what was the direction of his displacement for the entire trip?

Pls help ASAP. Pls show all work and calculations. Pls refer the first picture for the diagram and the second picture to answer all of the questions.

Use the diagram to answer the questions A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 2.29 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -1.71 m. What will the block s speed be when it reaches x = 0?   a. 5.01 m/s   b. 3.54 m/s   c. 1.06 m/s   d. 8.02 m/s Same type of track as in the previous problem, this time with d = 3.60 m. The block starts at x = 0, and is given a push to the left with an initial speed of 2.23 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down?   a. -0.25 m   b. -0.96 m   c. 0.96 m   d. 0.25 m
