Question

car attains a velocity of 7 ms-1 after 3 seconds when it accelerates at the rate of 2 ms-2. After

how long the car the car will attain a velocity of 11 ms-1

, if it is accelerated at the same rate.

What distance will it cover meanwhile. ​

Answer 1

Answer:

Initial velocity of the car u=0

Final velocity v=10 m/s

Time taken t=5 s

Using v=u+at

∴ 10=0+a×5

⟹ a=2 m/s
