Answer:

35000 KJ

Explanation:

The equation for the kinetic energy is given by the formula :

E_{k} = \frac{1}{2} mv^{2}

E_{k} = \frac{1}{2} (700)(10)^{2}

E_{k} = \frac{1}{2} (700)(100)

E_{k} = (350)(100)  OR E_{k} = \frac{1}{2} (70000)

E_{k} = 35000

Units will be kilojoules since the units of mass was kilograms .

Our final answer is 35000 KJ

Hope this helped and have a good day

An object in static equilibrium has a coefficient of static friction as 0.110. If the normal force acting on the object is 95.0
tatyana61 [14]

Answer : The mass of the object is, 86.3 kilograms

Solution :

The equation used for static friction is,

F_s=\mu_s\times N\\\\F_s=\mu_s\times (m\times g)

where,

F_s = force of static friction = 95 N

\mu_s = coefficient of static friction = 0.110

N = normal force

m = mass of the object

g = gravity on earth = 10m/s^2

Now put all the given values in the above equation, we get the mass of the object.

F_s=\mu_s\times (m\times g)

95N=(0.110)\times (m\times 10m/s^2)

m=86.3Kg

Therefore, the mass of the object is, 86.3 kilograms

A mover applies a net force of 28 N to a sofa that has a mass of 70 kg.
Alinara [238K]

Answer: .4 m/s^2= acceleration

Explanation:

f = m*a

We can rearrange this equation to solve for acceleration. Therefore,

a=f/m

a= 28N/70kg

a= 0.4 m/s^2
