Energy from minerals to heat energy which will later be used for fuel/electricity
Answer:
v0x = 104.89 m/s
The vector v0x will be:
v0x = (104.89 m/s, 0)
Explanation:
Please, see the attached figure for a better understanding of the problem.
To obtain v0x, we have to use this trigonometric rule:
cos θ = adjacent / hypotenuse
Seeing the figure, notice that the side adjacent to the angle θ is the x-component of the initial velocity v0. The hypotenuse is the magnitude of the vector v0. Then:
cos θ = magnitude v0x / magnitude v0
magnitude v0 * cos θ = magnitude v0x
151.0 m/s * cos 46 = magnitude v0x
magnitude v0x = 104.89 m/s
The vector v0x will be:
v0x = (104.89 m/s, 0)

Answer:
10-16= -4 so, 1.0x-4 is -4. So the answer is -4.
Explanation:
Answer:
70 mph
Explanation:
We can write the position of the car at time t as
where is the speed of the car, while the position of the truck is
where
is the initial distance between the car and the truck (at 3:00 pm)
is the speed of the truck
The car overcomes the truck when they have same position, so
This occurs at 4:30 pm, so 1:30 h (1.5 h) after the initial instant. So, by using
t = 1.5 h
And solving the equation for , we find the speed of the car:
