To settle an argument Dr Goulding and The Mrs (his wife) decide to have a 40.0 m long snowshoe race, with the prize being a very nice locally made face mask. At the start line they shake hands and when their cat helper Charlie fires the start gun they begin running on thier snowshoes. Dr Goulding reaches his maximum speed of speed of 2.68 m/s in a time of 10.0 s while The Mrs accelerates to her maximum speed of 3.00 m/s at a rate of a,-0.20 m/s2 How long does it take The Mrs to reach her maximum speed of 3.00 m/s?

It then slows down at a rate of 15m/s?. How much road is required to bring the car to a complete stop? The car lands 70 meters away from a nearby beach. Will the car run into water?
Planet X was just discovered orbitinga nearby star! It orbits a start that is 6.9 times themass of our sun in a solar system just 31.3 light-years away. The acceleration due to gravity thereis 0.07 g. After making some measurements in lab, you start to daydream about travel to other planets. Your spring gun can launch a projectile with a speed of 3.7 m/s. What would happen if you were tolaunch a projectile at an angle of 32 ° abovehorizontal on Planet X?

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.
You purchase the new Tesla Roadster and decide to take it out for a spin on theNewmarket Race Track. After getting to a top speed of 410. km/hr, suddenly atree falls down on the road blocking your path. You slam on your brakes to avoidhitting the fallen tree and thus, come to a complete stop. You were at a distanceof 30.0 m away from the tree when you hit the brakes. Assuming that theRoadster does not skid, what is the minimum deceleration needed to avoidhitting the fallen tree?
When last we left our friend Wile E. Coyote (SuperGenius), was peeling himself off a canyon wall and none the worse for wear. This time, he has obtained an Acme^ TM rocket-powered dragster with the AcmeTM Premium Parachute Braking System (patent pending)Starting from restthe dragster accelerates at a constant rate of 36.4 m/s ^ 2 for 14 seconds. At this point, the coyote realizes that he has passed the Road Runner and so he instantly cuts off the engine and deploys his braking system - which doesn't work. He therefore travels an additional distance of 1800 m at constant velocity until again becoming one with a canyon wall. Determine: (a) The total time for Wile E. Coyote's motion described above; on (b) The total distance covered by Wile E. Coyote's motion described above ; (c) The average velocity for Wile E. Coyote's motion described above.

Hello, I have already asked this question but the previous answer came back wrong when I checked it. A world record was set for the men’s 100-m dash in the 2008 Olympic Games in Beijing by Usain Bolt of Jamaica. Bolt “coasted” across the finish line with a time of 9.69 s. If we assume that Bolt accelerated for 3.00 s to reach his maximum speed, and maintained that speed for the rest of the race, calculate his maximum speed and his acceleration. Previeous answer: Maximum speed=v=8.9 m/smagnitude of acceleration =2.97 m/s2
