Starting from rest, a car travels 18 meters as it accelerates uniformly for 3.0 seconds. What is the magnitude of
omeli [17]

Answer:

a=4\frac{m}{s^2}

Explanation:

Hello.

In this case, for this uniformly accelerated motion in which the car starts from rest at 0 m/s and travels 18 m in 3.0 s, we can compute the acceleration by using the following equation:

x_f=x_0+v_0t+\frac{1}{2}at^2

Whereas the final distance is 18 m, the initial distance is 0 m, the initial velocity is 0 m/s and the time is 3.0 s, that is why the acceleration turns out:

a=\frac{2(x_f-v_ot)}{t^2} =\frac{2(18m-0m/s*3.0s)}{(3.0s)^2}\\ \\a=4\frac{m}{s^2}

Best regards.

What might be a reason conflict arises?
Katena32 [7]

D- all of the above

Explanation:

Conflict is a clash between different ideas and people.

  • It can be as a result of the misunderstanding of another person's point of view. This is one of the leading causes of conflict. A party can take another party's view verbatim without understanding the context behind a reasoning. Through this, conflict can ensue.
  • It can also be due to non-compatible personalities. This can be between an extrovert and introvert or a blend of them.
  • Different values can also lead to conflict. It can be a cultural or religious thing.

The three-toed sloth is the slowest moving land mammal. On the ground, the sloth moves at an average speed of 0.037 m/s, conside
Georgia [21]

Answer:

tortoise distance w.r.t sloth is 28.08 m further

Explanation:

given data

average speed v1 = 0.037 m/s

walking speed v2 = 0.076 m/s

time t = 12 min = 720 seconds

to find out

how much tortoise have gone wrt sloth

solution

we find here first tortoise walk that is

distance d1 = v2 × t

distance d1 =  0.076  × 720

distance d1 = 54.72 m

and sloth walk distance

distance d2 = v1 × t

distance d2 = 0.037 × 720

distance d2 = 26.64 m

and so

tortoise distance w.r.t sloth = d1 - d2

tortoise distance w.r.t sloth = 54.72 - 26.64 = 28.08

tortoise distance w.r.t sloth is 28.08 m further
