Answer:

2.63m/s^2

Explanation:

To solve this problem we use Newton's second law, which establishes a relationship between mass, acceleration and force applied to an object.

F=ma

Where F  is the force, m is the mass and a is the acceleration. Because they ask us for acceleration, we clear for  a:

a=\frac{F}{m}

And since we have the following information:

m=42.6kg and F=112N

the acceleration will be:

a=\frac{112N}{42.6kg}

a=2.629m/s^2≈ 2.63m/s^2

The answer is that the acceleration of the object is 2.63m/s^2

The answer is 2.63m/s^2! You use the formula F=ma, 112 = 42.6(a), a= 2.63m/s^2.

Select three different examples of accelerated motion. a body traveling in a straight line and increasing in speed a body travel
IrinaVladis [17]
This is the same question that I just answered.

Have present the definition of acceleration:

         a = Δv / Δt, this is change in velocity per unit of time.

a and v are in bold to mean that they are vectors.

1) a body traveling in a straight line and increasing in speed: CORRECT:

Acceleration is the change in velocity, either magnitude or direction or both. So, a body increasing in speed is accelerated.

2) a body traveling in a straight line and decreasing in speed: CORRECT

A decrease in speed is a change in velocity, so it means acceleration.

3) a body traveling in a straight line at constant speed: FALSE.

That body is not changing either direction or speed so its motion is not accelerated but uniform.

4) a body standing still : FALSE.

That body is not changind either direction or speed.

5) a body traveling at a constant speed and changing direction: CORRECT.

The change in direction means that the body is accelerated. The acceleration due to change in direction is named centripetal acceleration.

At a dock, a crane lifts a 2009 kg container 20 m, swings it out over the deck of a freighter, and lowers the container into the
deff fn [24]

Answer:

W = 157.5kJ

Explanation:

Assuming it moves the container at constant speed, the work done by the crane will be equal to the variation of the potential gratitational energy on the container:

Wc = \Delta E = m*g*(h2 - h1)  where h2= -8m  and  h1=0m

Wc = 157.5kJ
