A 20N force pulls to the right and friction pulls 5N. If the mass is 5kg, find the acceleration

Physics

Nikolay [14]3 years ago

Answer : The acceleration is, 3 m/s²

Explanation :

As, a 20 N force pulls to the right and friction pulls 5 N which is less.

Friction force is the force that applied to the opposite direction of the motion of an object.

That means, these two forces are applied in opposite direction.

So, net force will be, 20 N - 5 N = 15 N

Now we have to calculate the acceleration.

Formula used :

Force = Mass × Acceleration

Now put all the given values in this formula, we get:

15 N = 5 kg × Acceleration

Acceleration = 3 m/s²

Therefore, the acceleration is, 3 m/s²

So obviously the 20N pulls more than the 5N. Friction opposes direction of motion, so the 5N opposes the 20N and the two forces are against each other.

Net force would be in the direction of the 20N force: 20N - 5N = 15N.

Force = mass*acceleration
15 = (5)*acceleration
acceleration = 3m/s^2

Salma is riding her bicycle. She rides 25.6 kilometers in 4 hours. What is her speed?
Musya8 [376]

Answer:

6.4 kilometers per hour

Explanation:

Just do the amount of distance she covers divided by how many hours she rides to get the answer. In this case, its 25.6 divided by 4 which equals 6.4

You come across an open container which is filled with two liquids. Since the two liquids have different density there is a dist
Slav-nsk [51]

Answer:

526.57 Pa

Explanation:

P ( pressure at the bottom of the container) = 1.049 × 10^5 pa

Using the formula of pressure in an open liquid

Pw ( pressure due to water) = ρhg where ρ is density of water in kg/m³, h is the height in meters, and g is acceleration due to gravity in m/s²

Pw = 1000 × 9.81 ×0.209 = 2050.29 Pa

P( atmospheric pressure) = 1.013 × 10^5 Pa

Pl ( pressure due to the liquid) = ρ(density of the liquid) × h (depth of the liquid) × g

Subtract each of the pressure from the absolute pressure at the bottom

P(bottom) - atmospheric pressure

(1.049 × 10^5) - (1.013 × 10^5) = 0.036 × 10^5 = 3600 Pa

subtract pressure due to water from the remainder

3600 - 2050.29 = 1549.71 Pa

1549.71 =  ρ(density of the liquid) × h (depth of the liquid) × g

ρ (density of the liquid) = 1549.71 / (h × g) = 1549.71 / (0.3 × 9.81) =526.57 Pa

Explain the causes of atmospheric pressure and why it changes with altitude?​
Verdich [7]

Answer:

As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude

Why aren't humans as evolved as we think we are?
bezimeni [28]
Well there is many ways we are not evolved as much as we think we are from being we die from a lot of diseases to world hunger and other things to be honest humans are far from being really evolved in life we really need to focus on cures and solving world hunger and fighting among ourselves 

Hope this helps
