An automobile with an initial speed of 5.13 m/s accelerates uniformly at the rate of 3.0 m/s2. find the final speed of the car after 4.9 s. answer in units of m/s.

Final velocity v=19.83 m/sec

Explanation:

We have given initial velocity u =5.13 m/sexc

Acceleration of automobile

Time t =4.9 sec

We have to find the final velocity v

According to first law of motion v = u+at ,here v is the final velocity , a is acceleration and t is time

So

So the final velocity is 19.83 m/sec
