.A car skid for 290 m. assuming that the car skidded to a stop with a constant

snow_tiger [21]

Answer:

The speed of the car before it began to skid is 47.56 m/s.

Explanation:

We can use kinematics to solve this problem.

We are given three known variables:

Δx = 290 m
a = -3.90 m/s²
v = 0 m/s (final velocity is 0 m/s because the car skids to a stop).

We can use this kinematic equation to solve for the initial velocity, v₀.

v² = v₀² + 2aΔx

Substitute the known variables into the equation.

(0)² = v₀² + 2(-3.9)(290)
0 = v₀² - 2262
2262 = v₀²
v₀ = 47.56 m/s

The speed of the car before it began to skid is 47.46 m/s.

Balanced forces keep this boy in place on his chair. What

I am Lyosha [343]

While the boy is sitting on the chair it creates a force downward on the chair and therefore the chair takes it and gives off the equal amount of force. So while he is putting force downward the chair is putting the same force upward.

How would i solve these problems, nobody in my class understands and there is a substitute

DiKsa [7]

1) X-component: 568.5 N, Y-component: 511.9 N

2) The horizontal force is 86.6 N and the resulting acceleration is $0.87 m/s^2$

Explanation:

1)

In this first part of the problem, we have to resolve the force into its two components, along the x and the y direction.

The two components are given by:

$F_x = F cos \theta\\F_y = F sin \theta$

where

F = 765 N is the magnitude of the force

$\theta=42.0^{\circ}$ is the angle of the force with the horizontal

Substituting, we find:

Horizontal component: $F_x = (765)(cos 42.0^{\circ})=568.5 N$
Vertical component: $F_y = (765)(sin 42.0^{\circ})=511.9 N$

2)

First of all, we have to find the horizontal component of the pulling force, which is given by

$F_x = F cos \theta$

where

F = 100 N is the magnitude of the pulling force

$\theta=30.0^{\circ}$ is the direction of the force with the horizontal

Substituting,

$F_x = (100)(cos 30^{\circ})=86.6 N$

Now we can find the acceleration of the wagon by using Newton's second law:

$F_x = ma_x$

where

$F_x = 86.6 N$ is the net force in the horizontal direction

m = 100 kg is the mass of the wagon

$a_x$ is the acceleration in the horizontal direction

Solving for $a_x$ , we find

$a_x = \frac{F_x}{m}=\frac{86.6}{100}=0.87 m/s^2$

Explain how the first three steps of scientific inquiry are related.

Mademuasel [1]

The first three steps in scientific inquiry are related in that they are all equivalent to being on a fact finding mission. The three steps are to find or develop the question that must be answered, to study all related academic literature on the subject, and then to make a guess as to what the answer is.
I hoped I helped!
