Answer:
18m/s^2
Explanation:
Vf = Vi + at
t = distance/ average velocity
(120 + 0)/2 = 60 (average velocity)
400m/60m/s = 20/3 s
insert into first equation:
120 = 0 + a(20/3)
360 = 20a
18 = a

Answer:
magnetic trains works at the principle of repel on of the advantage is that they are fast and dont really need diesel
The relative ages of the moon's maria and highlands can be determined through the following:
- Radioactive dating
- Crater density
- Lava flows.
<h3>What is a Moon maria?</h3>
This is referred to as the early geologic units of the moon which arose from asteroid impact and subsequent volcanic activity.
The ages can be measured using techniques such as radioactive dating and crater density.

The force required to push the box upward is 145.3N and the force to pus the box downward is -109.3N
Data given;
- mass = 15kg
- angle = 30 degree
- acceleration = 1.2 m/s^2
- acceleration due to gravity = 9.8 m/s^2
<h3>Force against gravity</h3>
To move the plane upward, the box will move against gravity.
Let's solve for F
<h3>Force towards gravity</h3>
When the force pushes the box down the inclined plane, it moves towards gravity.
The force required to push the box upward is 145.3N and the force required to push the box downward is -109.3N
