2. Consider a football coach pacing back and forth along the sidelines. The diagram belowshows several of the coach's positions at various times. At each marked position, the coachmakes a "U-turn" and moves in the opposite direction. In other words, the coach moves fromposition A to B to C to D. What is the coach's resulting displacement and distance of travel?D.10 minO min-101020305040Position (yd

[Motion in R3] A roller coaster is going along a path. Wheeee! At a certain time t0 sec, the rollercoaster has position (in m) r(t0) = ⟨5, 2, 13⟩, velocity (in m/s) v(t0) = ⟨−2, 3, 2⟩ and acceleration (inm/s2) a(t0) = ⟨1, −3, 2⟩.(a) What was the speed of the roller coaster at this time?(b) Approximate the position of the roller coaster a quarter of a second later.(c) Was the roller coaster speeding up or slowing down?
Kayla throws a soccer ball out of her dorm window to Hafsa, who is waiting below to catch it. Kayla throws the ball at an angle of 40° below horizontal with a speed of 1.2 m/s, and Hafsa catches it 2.4 s later. How far from the base of the dorm does Hafsa stand to catch the ball, in meters? Use g = 10.0 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Starting from his nest, Sam the bird flies (level flight) in a straight line for 17 m at 65 ° north of east, and then in another straight line for 10 m due south, at which point he comes to rest on a power line. Back at the nest, Samantha (Sam's mate) flies in a straight line directly form the nest to where Sam is on the power line. ii) What is the (magnitude of the) angle between due east and the direction Samantha must fly to meet up with Sam? a) 25 ° b) 35 ° c) 45 ° d) 55 ° e) 65 °
A cat is sitting at one end of a long hallway. A mouse is running away from the cat, at a constant velocity of 1.47 m/s. When the mouse is 3.39 meters away from the cat, the cat gets up and accelerates from rest at a constant rate of 2.01 m/s? to catch the mouse. Round your answers to two decimal places. How much time does it take for the cat to catch the mouse? How far does the cat run before catching the mouse? Solve it correctly please. I will rate accordingly with multiple votes.
The biggest stuffed animal in the world is a snake 420 m long, constructed by Norwegian children. Suppose the snake is laid out in a park as shown in the figure below, forming two straight sides of a 95° angle, with one side 165 m long. Olaf and Inge run a race they invent. Inge runs directly from the tail of the snake to its head, and Olaf starts from the same place at the same time but runs along the snake.(a) If both children run steadily at 5.0 km/h, Inge reaches the head of the snake how much earlier than Olaf?(b) If Inge runs the race again at a constant speed of 5.0 km/h, at what constant speed must Olaf run to reach the end of the snake at the same time as Inge?

NASA is launching a rocket into space from Earth. This particular rocket burns its fuel for 5 minutes and then turns off its engines. At this point, the rocket keeps floating along through space at a speed of 10 km/s. What is the rocket’s average acceleration during these first 5 minutes? Part 2: How far did the rocket travel during the first 5 minutes? Part 3: The Moon is approximately 3.8.105 km from Earth. At its final speed, how long will it take the rocket to reach the Moon? Part 4: The star nearest to us, called Alpha Centauri, is 4.1.1013 km away. Could this rocket get a man to Alpha Centauri before he dies of old age? (This is a real obstacle to NASA’s plans of exploring other solar systems than our own!) Part 5: The rocket is half way to the Moon when its pilot suddenly notices he forgot his camera! He radios a second rocket crew on Earth and tells them to bring his camera and meet him on the Moon when he lands. Unfortunately, the second rocket can only…

Don’t answer these questions. Instead, draw a picture of the situation. Give names and labels to important pieces. Assign values to important pieces. Come up with an equation that relates pieces of the situation that might be helpful when answering the question. Don’t solve anything.2) A person is standing 350 ???? away from a model rocket that is fired straight up into the air at a rate of 15 ??/???. At what rate is the distance between the person and the rocket increasing 20 ??????? after liftoff
