Question

Atrauli while going down an inclined plane has an acceleration of 2 cm per second square what will be its velocity 3 seconds after the start

Answer 1

Hi.

Here is your answer---

___________________

Given---

Acceleration(a) = 2 cm/s²
Time(t) = 3 seconds.
Initial Velocity(u) = 0     [Since the car is starts from the Rest].

Using the Formula,

 Acceleration = (v - u)/t
                  2 = ( v - 0)/3
                   v = 6 cm/s

Thus, the Final Velocity of the Car after 3 seconds is 6 cm/s.

Hope it helps.

Have a nice day.

Answer 2

Answer:

Explanation: acceleration- 2cm/s square

Velocity after 3 sec will be:

First convert the cm into m

By 4 th equation of motion ( it is not the 4 th equation,as there are only 3 equations but, we can solve through it )

Equation- u+a*2 ( 2n-1 )

Here n is asked seconds

So try to find the Ans through it

Best of luck

Ans is 0.05m/s
