Answer:
magnitude v0x = v0 * cos θ = 31 m/s * cos 16° = 30 m/s
Explanation:
Please see the figure for a graphical description of the problem. As you can see from the figure, the vector v0 (initial velocity) is the sum of its horizontal and vertical components v0x + v0y.
Using the trigonometric rule for right triangles:
cos θ = adjacent / hypotenuse
We can calculate the magnitude of the v0x vector.
Seeing the figure, notice that the vectors v0, its horizontal component, v0x, and its vertical component, v0y, form a right triangle.
v0x is the side adjacent to the angle θ, and v0 is the hypotenuse of the triangle. Then:
cos θ = magnitude v0x / magnitude v0
magnitude v0x = magnitude v0 * cos θ = 31 m/s * cos 16° = 30 m/s

C=50.3 million miles. Using your hint v=(50.3 10^6)/(365.25 x 24 hrs)

radius of 98 million miles or a diameter of 196 million miles, giving a circumference of 615.75 million miles using the d=rt equation,
v=615.75 million/(365.24 days)=1.69 million miles per day, or .07 million miles per hour.
Answer:
in endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products! Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.
The SI unit of force is the newton, symbol N.
hope this helps!
