Distance= distance(initial)+v(initial)*t+0.5at^2
D=0+0*4+0.5*3*4^2
D=24 m

Answer:

24m

Step-by-step explanation:

Given parameters:

Initial velocity = 0m/s

Acceleration = 3m/s²

Time = 4s

Unknown:

Distance covered = ?

Solution:

To solve this problem, we apply the right motion equation:

S = ut +
(1)/(2)at²

S is the distance

u is the initial velocity

t is the time taken

a is the acceleration;

S = (0 x 4) +
(1)/(2) x 3 x 4²

S = 24m
