Verified answer
Given:
To find:
Solution:
Here , the initial velocity will be zero because the object is starting from rest
Now , using the 3rd equation of motion
S = ut + 1/2 at²
Where
Substituting the values we have
→ s = 0(1) + 1/2 × 8 × 1²
→ S = 0 + 4 × 1
→ S = 4 m
Hence , distance travelled = 4 m

About kinematics
Kinematics : Kinematics is a brach of mechanics which deals about the motion of the objects in 1D & 2D
Kinematic equations :
• Initial velocity = 0m/s
• Acceleration = 8m/s²
• Time = 1sec
• Distance travelled
According to the second equation of motion
Here:-
• s = distance
• u = initial velocity
Here we take initial velocity 0m/s because the body stars from rest
• t = time
• a = acceleration
Substituting the values:-
Hence:-
Other equations of motion:-
• v = u + at
• v² - u² = 2as
•
Note:-
These equations can only be applied when acceleration is constant. For variable acceleration, calculus should be used
