A car starts from rest and attains a velocity of 30m/s in 5 sec . calculate the total distance travel by that car and acceleration

Acceleration (a) = 6 m/s²

Total distance travel by car(s) = 75 meter

Explanation:

Given:

Initial velocity (u) = 0

Final velocity (v) = 30 m/s

Time (t) = 5 sec

Find:

Total distance travel by car(s) = ?

Acceleration (a) = ?

Computation:

v = u +at

30 = 0 + a(5)

30 = a(5)

Acceleration (a) = 6 m/s²

Total distance travel by car(s) = ut +1/2(a)(t)²

Total distance travel by car(s) = 1/2(a)(t)²

Total distance travel by car(s) = (0.5)(6)(5)²

Total distance travel by car(s) = 75 meter

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

answer: a. same unit
