Answer:
Distance = 45 meters
Time = 3 seconds
Step-by-step explanation:
Here, we want to calculate distance and time
To find the time, we can use one of the Newtons law of motion
V = U + at
In this question
V = final velocity = 18 m/s
U = initial velocity = 12 m/s
a = acceleration
Thus;
18 = 12 + 2(t)
18-12 = 2t
2t = 6
t = 6/2
t = 3 seconds
Mathematically we can also find the distance using one of the equation of motion;
D = ut + 1/2 at^2
D = 12(3) + 1/2 * (2) * 3^2
D = 36 + 9
D = 45 m
