Answer:

$\boxed {\boxed {\sf 2500 \ Newtons }}$

Explanation:

The formula for force is the product of mass and acceleration.

$F=m*a$

The mass of the car is 25 kilograms and the acceleration is 100 meters per square second. So,

$m= 25 \ kg \\a= 100 \ m/s^2$

Substitute the values into the formula.

$F= 25 \ kg * 100 \ m/s^2$

Multiply.

$F= 2500 \ kg*m/s^2$

1 kilogram meter per square second is equal to 1 Newton
Our answer of 2500 kg*m/s² is equal to 2500 Newtons

$F= 2500 \ N$

The force of the car is 2500 Newtons.

Answer:

2500 Newtons

Explanation:

If force equals the mass × acceleration then all should be quite simple

25kg is the mass of your car

100 m/s/s is the acceleration of you car

25kg • 100m/s/s = 2500 Newtons

Normal force is exerted _____to the surface of an object.

Elanso [62]

The normal force is always (underline, bold) is always perpendicular to the surface an object is sitting on. If the object is on an inclined plane, then the normal will not be vertical but it will be perpendicular to the angle of the incline.

The diagram below (left) shows a normal force (GH) that is not vertical, but it is perpendicular to the surface. The object on the right is the more usual normal a mass on a table top.

The vertical line on the right is the normal and it points up.

What is the magnitude of the impulse that would cause the 2-kg box to accelerate from 2 m/s to 5 m/s?

Law Incorporation [45]

6 J is the impulse caused by the change in velocity of 2 kg box from 2 m/s to 5 m/s.

Answer:

The magnitude of impulse is 6 J.

Explanation:

Impulse is the force acting on any object for a given time interval. As force is equal to the product of mass and acceleration and acceleration is the rate of change of velocity with time. Then the product of force with time interval will be equal to the product of mass with change in velocity.

F = m a = $\frac{m(v-u)}{(t_{2}-t_{1} )}$

FΔt = mΔv

Impulse = FΔt=mΔv

As the mass of box is given as 2 kg and the velocity changes from 2 m/s to 5 m/s, then the impulse = 2 × (5-2) = 2 ×3 =6 J

So 6 J is the impulse caused by the change in velocity of 2 kg box from 2 m/s to 5 m/s.

Find the net force and acceleration. 15 points. Will give brainliest!

gladu [14]

Answer:

$\boxed{F_{net} = 28.7 \ N}$

$\boxed{a = 2.1 \ m/s^2}$

Explanation:

Finding the net force:

Firstly , we'll find force of Friction:

$F_{k} = (micro)_{k}mg$

Where $(micro)_{k}$ is the coefficient of friction and m = 13.6 kg

$F_{k} = (0.16)(13.6)(9.8)\\$

$F_{k} = 21.32 \ N$

Now, Finding the net force:

$F_{net} = F - F_{k}\\F_{net} = 50 - 21.32\\$

$F_{net} = 28.7 \ N$

Finding Acceleration:

$a = \frac{F_{net}}{m}$

$a = \frac{28.7}{13.6}$

$a = 2.1 \ m/s^2$

We use towels to dry our body after taking a shower,why?

9966 [12]

Answer:

A wet body has a relatively high concentration of water. When this is transferred to a towel, the large surface area of the towel fabric distributes the water molecules over a much greater surface area, so the relative concentration is lower.
