Write down relevant equations, draw diagrams and show all of your work for full credit. 1. (20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is...

A car sitting at a red light begins to accelerate at 2 m/s2 when the light turns green. It continues with this acceleration until it reaches a speed of 20 m/s. It then travels at this speed for another few minutes. How far does the car travel in the first 45 s after the light changes to green?

A car sitting at a red light begins to accelerate at 2 m/s2 when the light turns green. It continues with this acceleration until it reaches a speed of 20 m/s. It then travels at this speed for another few minutes. How far does the car travel in the first 35 s after the light changes to green? Express your answer in meters to one significant figure.

I'm not sure what I'm doing wrong for the last question.
Starting from rest, a subway train accelerates to a speed of 20.0 m/s in tA20.6 seconds. The train travels at that speed for the next 21 seconds. Finally, the train decelerates steadily to a full stop over the next 10.3 seconds What is the train's acceleration at the beginning? 9709 m/s2 What is the train's deceleration as it comes to a stop? - 1.9417 m/s2 How far does the...

How
do you do this
A car starting from rest moves in a straight line with a constant acceleration of 1.95 m/s for 14.0 s, then slows down to a stop with a constant eceleration of 2.75 m/s How far does it travel? meters

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.6 m/s2 for 3 seconds. It then continues at a constant speed for 7.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 178.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

Please provide step by step directions on how you worked the
problem out
It was a dark and stormy night, when suddenly you saw a flash of lightning. Six and a half seconds later you heard the thunder. Given that the speed of sound in air is about 340 m/s, how far away was the lightning bolt? (Ignore the travel time for the flash of light.)
