Answer: The distance covered by a certain object which is travelling at a certain speed is calculated through the equation,
d = (V₀)t + 0.5at²
where d is the distance, V₀ is the initial speed, a is deceleration, and t is the time. Substituting the known values,
85 = (V₀)(t) + (0.5)(-0.43 m/s)(t²)
Because we are not given with the initial velocity, our answer would remain as the equation which is written above.

Answer:
A. Gasoline
B. Apple juice
Explanation:
A homogeneous mixture can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture.
For instance, aqueous hydrogen chloride, HCl(aq) is a homogeneous mixture. The aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride. This ultimately implies that, aqueous hydrogen chloride HCl(aq) is a solution of hydrogen chloride in water and it is commonly referred to as Hydrochloric acid.
Hence, the two mixtures that are homogeneous are gasoline and apple juice.
Answer:
x ’= 368.61 m, y ’= 258.11 m
Explanation:
To solve this problem we must find the projections of the point on the new vectors of the rotated system θ = 35º
x’= R cos 35
y’= R sin 35
The modulus vector can be found using the Pythagorean theorem
R² = x² + y²
R = 450 m
we calculate
x ’= 450 cos 35
x ’= 368.61 m
y ’= 450 sin 35
y ’= 258.11 m
