two bumper cars collide into each other and each caor jolts backwards what law is this isnt it newtons second law?

1 answer:

5 0

Yes because the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

An object is stopped at point ‘a’, and travels to point ‘c’ in 8s. What was its acceleration?

lutik1710 [3]

In SI units, its acceleration is (the distance from A to C) / 32 m/s^2 .

Subduction occurs at which of the following tectonic plate boundaries?

exis [7]

When two tectonic plates collide and form a converging plate boundry, normally one of the plates will slide underneath the other and that is when Subduction occurs.

A 4.00 m long, massless beam rests horizontally on a support 3.00 m from the left

Rus_ich [418]

If the beam is in static equilibrium, meaning the Net Torque on it about the support is zero, the value of x₁ is 2.46m

Given the data in the question;

Length of the massless beam; $L = 4.00m$

Distance of support from the left end; $x = 3.00m$

First mass; $m1 = 31.3 kg$

Distance of beam from the left end( m₁ is attached to ); $x_1 = ?$

Second mass; $m_2 = 61.7 kg$

Distance of beam from the right of the support( m₂ is attached to ); $x_1 = 0.273m$

Now, since it is mentioned that the beam is in static equilibrium, the Net Torque on it about the support must be zero.

Hence, $m_1g( x-x_1) = m_2gx_2$

we divide both sides by $g$

$m_1( x-x_1) = m_2x_2$

Next, we make $x_1$ , the subject of the formula

$x_1 = x - [ \frac{m_2x_2}{m_1} ]$

We substitute in our given values

$x_1 = 3.00m - [ \frac{61.7kg\ * \ 0.273m}{31.3kg} ]$

$x_1 = 3.00m - 0.538m$

$x_1 = 2.46m$

Therefore, If the beam is in static equilibrium, meaning the Net Torque on it about the support is zero, the value of x₁ is 2.46m

What type of animals does Dr. Grant study?

Rasek [7]

Dr. Alan Grant is the main protagonist in Jurassic Park, with the book written primarily from his perspective. He is a paleontology professor at the University of Denver and receives research funding from the Hammond Foundation. He became a world-renowned paleontologist after discovering dinosaur nest fossils in Montana. Billionaire John Hammond chooses Dr. Grant to evaluate his dinosaur amusement park because of his professional expertise and unbiased opinion on dinosaurs.

Idk if this is related to what you ask but it might help.
