To demonstrate the tremendous acceleration of a top fuel drag racer, you attempt to run your car into the back of a dragster that is "burning out" at the red light before the start of a race. (Burning out means spinning the tires at high speed to heat the tread and make the rubber sticky.) You drive at a constant speed of v0 toward the stopped dragster, not slowing down in the face of the imminent collision. The dragster driver sees you coming but waits until the last instant to put down the hammer, accelerating from the starting line at constant acceleration, a . Let the time at which the dragster starts to accelerate be t=0 . What is tmax, the longest time after the dragster begins to accelerate that you can possibly run into the back of the dragster if you continue at your initial velocity? i believe the only equation that would be required is v=d/t. it is the only one that i used but still got the incorrect answer. when i worked it out i thought the answer would be delta d/vo, but it wasnt the correct answer. it seemed perfect for an expression as an answer to the maximum time it would take for the car to collide with the dragster because when the dragster reaches vo which is the speed of the car, thats the last possible time they could possible collide right?
