the horizontal velocity would be equal to
Vh = sin (40) /60
= 0.74 * 60
= 44

the Vertical velocity would be equal to

General internal energy expression:
Uf = (Ui-W) + Q
Where Uf = Final internal energy, Ui = Initial internal energy, W = Work done, Q = Heat added
But,
Uf -Ui = ΔU = 36 J, W = 17 J. Then,
ΔU = -W +Q => Q = ΔU+W = 36+17 = 53 J
Therefore, heat added to the system is 53 Joules
yes, just like human skin. The bigger you grown the more your skin stretches, I a fish is bigger their skin will stretch leading to broad stripes.
Fossil fuels like coal for instance , when they are provided with heat energy (heating them) they start producing Kinetic energy . This kinetic energy will be passed along a turbine which transforms this K.E to an electrical energy used in different useful forms.
The slope is always
(the change in 'y')
divided by
(the change in 'x') .
This line is so easy ... it crosses all the corners of the boxes,
so you have tons of choices of what 2 points to pick.
But let's just pick the ends of the line.
From the beginning to the end of the line:
-- the change in 'y' is 4 meters
-- the change in 'x' is 40 seconds
Slope = (the change in 'y') divided by (the change in 'x') .
= (4 meters) / (40 seconds)
= 0.1 meter/second .
