Given,
The initial velocity of the car, u=0 m/s
The final velocity of the car after 10 seconds, v₁=25 m/s
The time periods, t₁=10 s
and t₂=6s
First, we need to find the acceleration of the car, in order to find the velocity of the car after 6 seconds.
From the equation of the motion,
Where a is the acceleration of the car.
On substituting the known values in the above equation,
To find the velocity of the car after 6 seconds, we use an equation of the motion,
On substituting the known values,
Therefore the acceleration of the car after 6 seconds is 15 m/s.
