A car is travelling at 30.0 m s'' when the driver needs to stop suddenly. If the driver takes 0.250 s (the reaction time) to apply the brakes, and the maximum deceleration of the car is 8.00 m s. a) Determine the distance travelled before the driver applies the brakes, (the reaction distance). b) Determine the braking distance (the distance travelled after applying the brakes). c) Determine the total stopping distance.

My number for initial velocity or 2.0, Final velocity is 15 m/s, Time is n/a, distance is 85, so what is acceleration
A runner runs the length of a 100-m in 20 seconds. What is her speed in m/s? If she runs with the same speed, how long (in seconds) will it take her to run the length of a 250-m track ?
My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she runs 4.12 meters from the middle of our living room to our kitchen, where she is satiated with her grub. If it takes her 4.45 s to get to the kitchen, what was her speed in m/s to the nearest hundredth?
My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she accelerates from rest 2 ft/s2 towards the kitchen. If it took her 2.65 seconds to get to the kitchen, what was her final speed in ft/s2 when she got to her dinner bowl?
The record time for a 1/4 mile drag race is 4.428 sec with a final speed of 152 m/s (336 mph). If the driver continued at this acceleration how far would it have traveled 1 minute?
here is my problem, I need help: One simple model for a person running the 100 mm dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.1 m/sm/s in 2.64 ss , what will be his total time? Express your answer in seconds.
What is the velocity and distance covered in 5 seconds when acceleration is 0.02s^(-7/8)) m/s², where s is in meters?
Sam crossed the finish line of a 100m race with a speed of 10.44m/s. If it took him an additional 3.2s to come to a complete stop after crossing the finish line then calculate his acceleration after crossing the finish line. Also how far after crossing the finish line did he come to a complete stop?
Professional baseball player Nolan Ryan could pitch a baseball at approximately 160.0 km/h. At that average velocity, how long did it take a ball thrown by Ryan to reach home plate, which is 18.4 m from the pitcher’s mound? Compare this with the average reaction time of a human to a visual stimulus, which is 0.25 s.
Two trains are moving at 30 m/s in opposite directions on the same track. The engineers see simultaneously that they are on a collision course and apply the brakes when they are 1000 m apart. Assuming both trains have the same acceleration, what must this acceleration be if the trains are to stop just short of colliding?
Bacteria move back and f01th by using their flagella (Structures that look like little tails). Speeds of up to 50m/s(50106m/s) have been observed. The total distance traveled by a bacterium is large for its size, while its displacement is small. Why is this?
The 1992 world speed record for a bicycle (human-powered vehicule) was set by Chris Huber. His time through the measured 200m stretch was a sizzling 6.509 s, at which he commented "Cognito ergo zoom". In 2001, Sam Whittingham's beat Hubert's record by 19.0km/h. What was Whittingham's time through the 200m? (hint: d=rt).
