Allushta [10]
\text{slope}=\frac{y_2-y_1}{x_2-x_1}

(-2, -1)(3, 1)

Therefore,

\text{slope}=\frac{1-(-1)}{3-(-2)}=\frac{1+1}{3+2}=\frac{2}{5}

Calcular la aceleración que produce una fuerza de 40 N sobre un cuerpo con 88 Kg de masa. Expresar el resultado en m⁄s^2 *
tigry1 [53]

Answer:

a = 0.45 m/s²

Explanation:

The given question is ''Calculate the acceleration that produces a force of 40 N on a body with 88 kg of mass".

Given that,

Force, F = 40 N

Mass of the body, m = 88 kg

The net force acting on the body is given by :

F = ma

Where

a is the acceleration of the body

a=\dfrac{F}{m}\\\\a=\dfrac{40\ N}{88\ kg}\\\\a=0.45\ m/s^2

So, the required acceleration is 0.45 m/s².

A man pushes a 34 kg lawn mower using a handle inclined 45.0 ∘ from the horizontal. He pushes with 75 N directed along the handl
tresset_1 [31]

Answer:

333 N

Explanation:

The weight of an object is given by:

W=mg

where

m is the mass of the object

g is the acceleration of gravity

For the mower in the problem,

m = 34 kg

Also

g=9.8 m/s^2

So, the weight of the mower is

W=(34)(9.8)=333 N

How objects on Earth are affected by gravitational force.
stellarik [79]

Answer:

The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it
