Answer:

Vo = 4.5 [m/s]

Explanation:

In order to solve this problem, we must use the following equation of kinematics.

v_{f}=v_{o}+a*t

where:

Vf = final velocity = 12 [m/s]

Vo = initial velocity [m/s]

a = acceleration = 1.5 [m/s²]

t = time = 5 [s]

Now replacing:

12=v_{o}+1.5*5\\v_{o}=12- (7.5)\\v_{o}= 4.5[m/s]

Snowcat [4.5K]
Size is in relation to distance(how far across or around)mass is measuring how much there is, mass is related to both size and DENSITY, EX: A balloon has a large size but a tiny mass, compared to a bowling ball, which has a similar size but a much larger mass

What is the relationship between a planet’s distance from the sun and the length of its year? Explain.
laila [671]

Answer:

Planets that are close to the sun have shorter years, and planets that are farther have longer years, because of how fast/slow it orbits the sun.
