Answer:
The velocity after 1.5 s is 22.7 m/s downwards.
Explanation:
Initial velocity = - 8 m/s
acceleration, a = - 9.8 m/s2
time, t = 1.5 s
Use first equation of motion
v = u + at
v = - 8 - 9.8 x 1.5
v = - 8 - 14.7
v = - 22.7 m/s
Thus, the velocity after 1.5 s is 22.7 m/s downwards.
The magnitude of the gravitational attraction is 
.
Explanation:
The magnitude of the gravitational force between two objects is given by
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
In this problem, we have
is my mass
The mass of the mountain is 100 million tons, and keeping in mind that
1 ton = 1000 kg
The mass of the mountain is
The distance between me and the mountain is
r = 1 km = 1000 m
Therefore, the gravitational attraction is

<u><em>It's called geothermal energy, and is present due to the incredible amount of heat present in Earth's interior from radioactive decay, friction, and residual heat from Earth's formation.</em></u>
East is our x axis
north is out y axis N

so he moves 3 m to the right and then 4 upwards
imagine what that looks like.......... a right angle triangle
therefore we can use Pythagorean theorem
let the unknown side be x, which is the hypotenuse in this case
x^2 = 3^2 + 4^2
x^2 = 9 + 16
x^2 = 25
take the square root
x = 5
5 is your magnitude and the direction is NE( North East) or positive direction
