Motion is changing all the time. When you stand up, begin to run, or turn a corner, your motion is changing. These changes in mo

tion all have something in common. They all start with a push or a pull. What happens when you push or pull an object? Make a claim about how a push or pull affects the motion of a water tube.

A friend claims that her car can accelerate from a stop to 60 mi/h (26.8 m/s) in 5.1 s , but the speedometer is broken. You deci
Lemur [1.5K]

I attached a diagram, according to the description given, to better understand the problem. The car accelerates, at a 'a' speed, which will also experience the hanging object, in two components:

The one in x, with 'a' in the opposite direction to the car's address

The one found in y, the product of gravity. The two components are related through the tangent and the respective angle, as well,

tan\theta = \frac{ma}{mg}

tan\theta = \frac{a}{g}

To identify, we know that it can be expressed as a function of speed,

a= \frac{\Delta v}{t} = \frac{v-u_0}{5.1}\frac{26.8}{5.1}

a=5.26m/s^2

Replacing in our angle formula,

tan\theta = \frac{5.26}{9.8}

tan\theta = 0.54

\theta = tan^{-1}(0.54)

\theta = 28.4\°

If there is no friction, we consider the vertical forces of both the Washes and the Normal car. So,

F=ma

Therefore the relationship with the vertical component would be given by,

\Rightarrow \frac{F}{mg} = \frac{ma}{mg} = \frac{a}{g}=\frac{5.26}{9.8}=0.54 =54\%

What causes a satellite to move tangentially to a circular path?
yawa3891 [41]

Explanation : We know that two forces acting on the satellite.

The speed of the satellite and the force of the gravity on the satellite then the result , the satellite moves around the earth in a circular motion.

A satellite to move tangentially to a circular path, while revolving around the circular path because the centripetal force is acting on it.

So, we can say gravity is responsible for the motion of the satellite in a circular path.
