What is the passengers velocity on the vertical drop of the tower of terror at Disney world if the distance for the drop is 50m,
andrey2020 [161]

Assuming constant acceleration due to gravity of a=9.8\,\dfrac{\mathrm m}{\mathrm s^2}, and assuming the passengers start at rest, so that v_0=0\,\dfrac{\mathrm m}{\mathrm s}, we have

v=v_0+at\implies v=\left(9.8\,\dfrac{\mathrm m}{\mathrm s^2}\right)(5.5\,\mathrm s)=53.9\,\dfrac{\mathrm m}{\mathrm s}

or 54 m/s if taking significant digits into account.

Which statement BEST compares the force of gravity on a school bus on a school day and a weekend? *
inna [77]

Answer:

(A) The force would be lower on the school day than the weekend.

Explanation:

In  a  school  day  the  bus  is  on  the  road  travelling  with  kids.  But  in  a  weekend  it  is  parked.  When  a  object  stays  still  that  means  the the  force  which  is  working  on  the  earth  by  the  bus  is  equal  to  the  force which  works  on  the  bus  by  the  earth. we  can  understand  it  clearly by,  Newton's second law of motion.  

This pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.  so  as  it  is  when  it  is  balanced  it  is  not  moving.

And  on  a  school  day  the  bus  is  moving  so  it  has  a  force  pulling  itself  forward .  so  it  means  that  the  force  which  the  bus  has  is  greater  than  the  gravitational  force.

How much force is required to hold an empty carton of volume 1.5 L beneath the surface in a sink of water? Assume the carton is
Gwar [14]

Answer:

It will require 14.715 N of force to hold the cartoon beneath the water.

Explanation:

Given the the volume of cartoon is 1.5 liters.

We need to find the force required to hold this cartoon beneath the water.

As we know from the Archimedes principle that the net force is equal to the volume of liquid displaced.

Given volume of the cartoon is 1.5 liters. So, 1.5 liters of water will be displaced.

And we know the density of the water is 1000\ kg/m^3. That is 1\ kg/L

And g=9.81\ m/s^2

F_N=\rho Vg\\F_N=1\times 1.5\times 9.81\\F_N=14.715\ N

So, it will require 14.715 N of force to hold 1.5 liter volume of cartoon beneath the water.
