1. The problem statement, all variables and given/known data A car moving with uniform acceleration covers 450m in a 5 second interval, and covers 700m in the next 5 seconds interval. The acceleration of the car is ? 2. Relevant equations 3. The attempt at a solution please correct me if i am wrong, i calculate velocity at the end of the first run i.e. v1= 450/5= 90m/s . And then at the end of 2nd run v2= 700/5 = 140 m/s. Then i apply, Acceleration =change in velocity upon time period i.e. (140-90)/5 = 10m/s^2 , right? Thank you.
