a person runs with an initial velocity of 5.0m/s. then he slows down at a rate of -1.2 m/a square over a period of 3 seconds
A car is initially moving at 9.9 m/s in the positive x direction and accelerates at a constant acceleration of 3.4 m/s2 in the positive x direction for 6 seconds. It then immediately has an acceleration of 6.6 m/s2 in the negative x direction. After some time, its velocity is 27.6 m/s in the negative x direction. What is the average velocity for the entire trip in m/s? Indicate the negative x direction by including a negative sign but do...
A train moving east with an initial velocity of 0.500 m/s speeds up at 2.00 m/s for 20.0 seconds, then moves at constant velocity for 100. seconds and finally slows down to a stop during the final 30.0 seconds. (10 points) a. Sketch a position versus time graph for the train #1 2 Sketch a velocity versus time graph for the train use c. What was the acceleration as it slowed? d. What was the net displacement during the 150...
At the end of a race a runner decelerates from a velocity of 8.70 m/s at a rate of 2.40 m/s2. How far in meters does she travel in the next 4.10 s? (Assume the deceleration of 2.40 m/s2 is constant over the full 4.10 s.) m What is her final velocity in m/s? Evaluate the result. Does it make sense?
An object is originally moving at 3.5 m/s in the negative x direction with a constant acceleration of 2.4 m/s2 in the negative x direction for 5.1 seconds. Then (immediately) a constant acceleration is applied to in the positive x direction. After some time, the average velocity for the entire trip is 0 m/s., and at that time, the object is moving at 61.2 m/s in the positive x direction. How long was the acceleration applied in the positive x...
Here is a simple problem involving a single step. A particle moving in the positive direction of an x axis slows from 50.0 m/s to 20.0 m/s at the rate of 4.00 m/s2.
