Check the full answer on App Gauthmath. The distance travelled by car before it rolls back is 260. Create an account to get free access.
Crop a question and search for answer. In this year's recruitment cycle, a total of 3539 vacancies were released. The car travels: - With a uniform acceleration of 2 m / s2. Unlimited access to all gallery answers. The car is traveling on the slope inclined at the angle the gas runs out, then the car would stop and starts rolling back. What is the acceleration of a car that travels in a straight line at a constant speed? Average speed: The average speed of a particle for a given 'Interval of time' is defined as the ratio of total distance travelled to the time taken i. e. CALCULATION: Given - v = 8 m/s at t = 4 s. From the given table we can find uniform acceleration, As we know that acceleration is defined as the rate of change of velocity i. e., Thus car travels with a uniform acceleration of 2 m / s2.
QuestionDownload Solution PDF. CONCEPT: - Uniform acceleration: A body is said to have uniform acceleration if the magnitude and direction of the acceleration remain constant during particle motion. We solved the question! 5 m/s²what is the cars speed after 4.
