The car's acceleration, given the data from the question is 4 m/s²

<h3>Data obtained from the question</h3>

The following data were obtained from the question:

  • Initial velocity (u) = 13 m/s
  • Distance (s) = 50 m
  • Time (t) = 5 s
  • Acceleration (a) = 9.8

<h3>How to determine the acceleration of the car</h3>

The acceleration of the car can be obtained as illustrated below:

s = ut + ½at²

50 = (0 × 5) + (½ × a × 5²)

50 = 0 + (½ × a × 25)

50 = 0 + 12.5a

50 = 12.5a

Divide both sides by 12.5

a = 50 /12.5

a = 4 m/s²

Thus, the acceleration of the car is 4 m/s²

How do you do this?Or what are the formulus
LuckyWell [14K]
You got the formulas on the sheet on the top :) So just use those, exchanging v (as in velocity, expressed in m/s) and the d (in meters) and t (in seconds). Hope you will manage it.

The mass of the block in the drawing is 10 kg. The coefficient of static friction between the block and the vertical wall is 0.5
antiseptic1488 [7]

Answer:

The minimum force to start the block moving up the wall = 49 N

Explanation:

Friction: This is the force that tend to oppose the motion of two bodies in contact. The S.I unit of frictional force is Newton (N)

The minimum force required to start the block moving up the wall = Frictional Force.

I.e F = Frictional force.

And, F = μR..........................Equation 1

Where μ = coefficient of static friction, R = Normal reaction.

But R = mg ( on a level surface).................. Equation 2

Where m = mass, g = acceleration due to gravity.

Given: m = 10 kg,

Constant: g = 9.8 m/s²

substituting these values into Equation 2

R = 10 × 9.8

R = 98 N.

Also given: μ = 0.50

Substituting these values into equation 1

F = 98 × 0.5

F = 49 N.

Therefore The minimum force to start the block moving up the wall = 49 N

According to Kepler's law of harmonies, which of these planets takes the longest to orbit the Sun? Mars Jupiter Venus Neptune
tino4ka555 [31]
NEPTUNE is the planet that takes the longest to orbit the Sun.

According to Kepler's law of harmonies, Planets closer to the Sun orbit it in a shorter time period than planets further from the Sun.

Planets arrangement from the Sun.
1) Mercury
2) Venus
3) Earth
4) Mars
5) Jupiter
6) Saturn
7) Uranus
8) Neptune
9) Pluto

So based on the given choices and arranged according to the longest to orbit to the shortest to orbit, the order would be: Neptune, Jupiter, Mars, and Venus

According to the law of conservation of mass, how would the masses compare?
Zarrin [17]

Explanation:

According to the law of conservation of mass, the masses at the start and finish of a reaction will stay the same. The law of conservation of mass "mass is always constant in a chemical reaction".

  • The law is the basis for chemical calculations.
  • Masses of reactants and products must be the same to show that mass is always conserved.
  • Disparity in the mass could result from loss of mass to the environment or some side reactions that cannot be easily monitored.
