No the substance will remain the same substance as before.
The momentum of an object is the product between the mass m of the object and its velocity:
The truck in our problem has momentum equal to
and a mass of
so, if we re-arrange the previous formula, we can use these data to find the velocity of the truck:
Answer:
θ = 56.09°
Explanation:
Given that
h = 8.5 ft
speed ,u= 28 ft/s
We know that acceleration due to gravity g
g= 32.2 ft/s²
The maximum height h is given as
Now by putting the values
θ = 56.09°
Therefore the angle will be θ = 56.09°
