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:
Solar system is nested nearly 2/3 of the way from the center of the galaxy to the outskirt of the galactic disc.
Thermal energy moves between objects through conduction. This is because, collisions made from the objects through the molecules.
Heat can also move in three different ways. Convection, conduction, and radiation.
