- I am doing a free-fall experiment for Physics and I need to make a velocity vs. time graph using the average value of the final velocity. Do you know how I would be able to find the values for the velocity vs. time graph? The average value of the final velocity is 6.21954 m/s. It is question #9.I looked at the motion diagram and thought it was representing an object accelerating to the right and getting faster. I thought A and B were right, but my first thought was that C looked like it could be moving to the right and slowing down, could you explain why this is wrong? I tend to get these types of questions wrong.To help travelers get around the airport, a shuttle was built between two terminals. Starting from rest, the shuttle accelerates at 0.447 m/s2 for 37.1 s, cruises at this constent velocity for 62.5 s, and then deaccelerates at -0.275 m/s2 until it comes to a stop. What is the distance between the terminals?
- Car A was traveling east at high speed when it collided at point O with car B , which was traveling north at 45 mi/h. Car C , which was traveling west at 60 mi/h, was 32 ft east and 10 ft north of point O at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they hit the utility pole p. Knowing that the weights of cars A, B, and C are, respectively, 3000 lb, 2600 lb, and 2400 lb, and neglecting the forces exerted on the cars by the wet pavement, solve the problems indicated.Knowing that the coordinates of the utility pole are xp= 46 ft and yp = 59 ft, determine (a) the time elapsed from the first collision to the stop at P,(b) the speed of car A.An object moves along the positive x-axis with a speed of V, =8 m/s for 2 seconds, then moves along the negative x-axis with a speed of V2 =14 m/s for 2 seconds and then moves along the positive x-axis with a speed of V3 =25 m/s for 2 seconds What is the average speed of the object (m/s)? A. 47 B. 15.67 C. None D. 31.33 E. 62.67Two students are discussing the motion of an object as it falls close to the earth. Jerry makes the following statement: "The velocity of an object when it is falling close to the earth never changes because acceleration due to gravity is constant. " Susan does not agree with Jerry. Which reason below should Susan give to Jerry to correct his misconception? The velocity of an object falling close to the ground is always decreasing because gravity is negatively accelerating that object. The velocity of an object falling close to the ground is always decreasing because gravity is constantly accelerating that object. The velocity of an object falling close to the ground is always increasing because gravity is increasingly accelerating that object. The velocity of an object falling close to the ground is always increasing because gravity is constantly accelerating that object.
