Acceleration Problems. 1. A poorly tuned Geo Metro can accelerate from rest to a speed of 28 m/s in 20 s. a. What is the average acceleration of the car? b. What distance does it travel in this time? 2. At t = 0 a car has a speed of 30 m/s. At t = 6 s its speed is. 14 m/s. What is its average acceleration during this time interval? Time (s) 3.
The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.
BE SURE TO WRITE THE EQUATION EACH TIME AND PLUG IN THE NUMBERS AND UNITS IN THE CORRECT PLACES. ALSO SHOW THE ANSWER WITH CORRECT UNITS. A car increases it’s velocity from 0 m/s to 14 m/s in 2 seconds. A bicycle rider increases his speed from 5 m/s to 15 m/s in 10 seconds.

Calculate the time it takes to travel a distance of 672 km at a speed of 96 km/h. 15. A beetle travels at a speed of 0.09 m/s, it travels a distance of 1.08 m before it is caught
Question 1 :-A body is covering distance in proportion to square of time. The acceleration of the body is (a) increasing (b) decreasing (c) zero (d) constant Answer:- (d) Question 2:-The relation between $t$ and distance $x$ is $t=\alpha x^2+\beta x$. Where $\alpha$ and $\beta$ are constants.
t (s) bus is moving at 20 m/s. The bus starts to break, and finally reaches a speed of 0 m/s. The bus took 5 seconds to stop. Which of the following ways would be the correct way to find the acceleration of the bus? Explain how you know. a. a = (0 – 20 m/s)/5s. b. a = 5s * (20 m/s) c. a = (20m/s - 0)/5s.
