'A car and train move together along parallel paths at25.0 m/s, with the car adjacent to the rear of the train.Then, because of a red light, the car undergoes a uni-form acceleration of - 2.50 m/s² and comes to rest. Itremains at rest for 45.0 s and then accelerates back to aspeed of 25.0 m/s at a rate of 2.50 m/s². How far be-hind the rear of the train is the car when it reaches thespeed of 25.0 m/s, assuming that the speed of the trainhas remained 25.0 m/s?

You are driving along a straight section of road at 13 m/s when 10 m in front of you a furry creature jumps out into the middle of the road. You instantly slam on your breaks, but the breaks lock so that you slide along the pavement with kinetic coefficient of friction between the tires and the pavement of 0.65. By what distance do you stop short of running over the furry creature or by what distance is your roadkill dinner behind you when your car finally comes to a halt? Note that the total mass of the car (including you) is 1360 kg, while the mass of the furry creature is 2.6 kg.

Hi, I need help with this physcis problem. I've gone over it multiple times and can't firgure it out. Anyway you can help? A car, initially at rest, accelerates at a constant rate of 2 m/s2 due east (choose east as the positive direction; round your answer to the nearest meter per second; include units)What is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? What is its velocity after 4 seconds? What is its velocity after 5 seconds? What is its velocity after 9 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due eastWhat is its velocity after 1 second? What is its velocity after 2 seconds? What is its velocity after 3 seconds? If instead a car accelerates at a constant rate of 5 m/s2 due westWhat is its velocity after 1 second?
A particle is initially at rest at the origin at t = 0.00 s. From t = 0.00 s to t = 5.00 s its velocity changes according to v(t) = (3.20 m/s2)t. From t = 5.00s to t = 11.00s its velocity changes according to v(t) = (16.00 m/s) - (1.50 m/s2)(t - 5.00 s). From t = 11.00 s to t = 20.00 s its velocity does not change. What is the position of the particle at t = 16.54?
