A sprinter in a 100m race accelerates from rest at a rate of 5.0m/s^2. She maintains this acceleration for a period of 6.0s. Once she has reached her top speed, she continues to run at her top speed for the rest of the race. Q. calculate the total time take for the sprinter to run the 100m race. - how do I get the time while accelerating and time while at constant velocity? Could you please explain how EASY and...
A particle, starting at rest, accelerates at 5 m/s2 for 10 s. It
then decelerates to 30 m/s over a period of 10 s. The particle then
moves at a constant speed for 20 s before decelerating to zero over
a period of 5 s.

A particle, starting at rest, accelerates at 5 m/s2 for 10s. It then decelerates to 30 m/s over a period of 10s. The particle then moves at a constant speed for 20s before decelerating to zero over a period of 5s. Plot the velocity and acceleration of the particle as functions of time. What is the total distance traveled by the particle?
A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.
A subway trauma accelerates from rest at one station at a rate of 1.2 m/s^2 for half of the distance to the next station, then decelerates at this same rat for the final half. If the stations are 1100 m apart, find: a. The time of travel between stations b. the maximum speed of the train.

(b) How much time does blood take to reach its final velocity? s 2. A car is traveling at 11.0 m/s, and the driver sees a traffic light turn red. After 0.570 s (the reaction time), the driver applies the brakes, and the car decelerates at...
Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.
A speedboat starts from rest and accelerates at +2.20 m/s2 for 8.87 s. At the end of this time, the boat continues for an additional 4.43 s with an acceleration of +0.626 m/s2.
