An object with a density of 941.0 kg/m3 and a mass of 1039.0 kg is thrown into the ocean. Find the volume that sticks out of the
STatiana [176]

The volume that sticks out of the water is 83 m³.

To find the answer, we need to know about the archimedes principle.

<h3>What's archimedes principle?</h3>
  • It says that when an object is on a water surface, the amount of force on the object is equal to the weight of water displaced by it.
  • Mathematically, weight of the object= weight of water displaced

<h3>What's the volume of an object remain on the water surface, if the density and mass of the object are 941.0 kg/m³, 1039.0 kg respectively?</h3>
  • Let V = volume of the object,
  • v= volume of water displaced
  • V-v = volume that sticks out of the water
  • Weight of the object = V× density of object × g
  • Weight of water displaced= v× density of water × g
  • As per archimedes principle, V× density of object × g=v× density of water × g
  • V-v = density of water - density of object

= 1024 - 941 = 83 m³

Thus, we can conclude that the volume that sticks out of the water is 83 m³.

An automobile of mass 2500 kg moving at 49.4 m/s is braked suddenly with a constant braking force of 8,868 N. How far does the c
BaLLatris [955]

Answer:

344.68 m

Explanation:

The computation of the far does the car travel before stopping is

Data provided in the question

Force = F = 8,868 N

mass = m = 2,500 kg

So,

accleration = a is

= \frac{-F}{m}\\\\\= \frac{8868}{2500}

a = -3.54 m/s^2

The initial speed = u = 49.4 m / s

final speed = v = 0

Based on the above information

Now applying the following formula

v^ 2- u^ 2= 2aS

Therefore

S = \frac{v^ 2- u^ 2}{2a}\\\\\ =  \frac{0- 49.4^ 2}{2\times -3.54}

= 344.68 m
