a simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reqching top speed, then maintains that speed through the finish line. Assume the sprinter reaches her top speed of 10.2 m/s in 11.5m

(a) draw and label a diagram of the above and below information.
(b) what is her acceleration (in m/s^2) during the first 11.5 m?
(c) how much time (in sec) has elapsed when she reaches her top speed
(d) what will be her total time( in sec ) for the 100m dash

A sprinter is practicing her starts on a 100 m long straight track. From rest, she starts running with an acceleration of 4.2 m/s2 until she reaches her top speed of 10 m/s. Once up to speed, she immediately relaxes, decelerating slowly at a rate of -1.3 m/s2 until she comes to a stop. (a) Draw the motion diagram (including velocity vectors) for the sprinter. Please label her starting point and end point, and where she reaches her maximum speed....

Kathy is running a 100 m race. When the starter’s pistol fires, she leaves the starting block and continues speeding up until 4 s into the race, when she reaches her top speed of 9 m/s. She holds this speed for 5 s; then her speed has slowed to 7 m/s by the time she crosses the finish line 12 s after she started the race. The data for the race is presented in table below. Time (sec) Velocity (m/s)...

A sprinter runs a 100 metre race. He does not move for 0.2 seconds after the starting pistol is fired. Then his velocity vms-1 increases as v(t) = -0.5t2 + 5t - 0.98 where t is time in seconds. he reaches his maximum speed and maintains this until he crosses the finish line. Calculate his time to complete the race.

Usain Bolt is capable of running a 100 m dash race in 9.58 s, or about 23.4 mph. Suppose you are traveling in space during the race and moving at 90% the speed of light. What average speed to you observe Bolt to run the race at, in mph? In the previous problem, the observers on Earth and on the spaceship measure two different speeds, so who is right? Bolt can’t be running at two different speeds at the same...

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...

Design a "bungee jump" apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 12 m long, and that the cords stretch in the jump an additional 19 m for a jumper whose mass is 120 kg, the heaviest adult you...
