A particle moves along X direction with constant acceleration. it velocity after 4s is 18 m/s and displacement is 56m find out its initial velocity and acceleration?
1 Answer
Initial velocity:
Acceleration:
Explanation:
We're asked to find the initial velocity
To find the initial velocity, we can use the equation
We'll take the initial position
Plugging in known values, we have
The initial velocity is thus
Now that we know the initial velocity, we can use the equation
to find its acceleration. Rearranging the equation to solve for
The acceleration of the particle is thus constant at
