Physics question: show work and circle answer

Physics
1 answer:
ruslelena [56]2 years ago
5 0

Answer:

F = 2 [N], choose option (2)

Explanation:

The principle of impulse is defined by the following expression:

Impulse = Force * Time

Force = force acting [N] or [kg*m/s^s]

Time = time during the impulse [s]

Replacing:

Impulse = 10[kg*m/s^2] * 10 [s]

Impulse = 0,1 [kg*m/s]

Now with this impulse, we can find the force for the new time.

F = Impulse/Time

F = 0.1[kg*m/s] / 0.05[s]

F = 2 [N]

Answer:

A: In all cases, the acceleration was the same.

Explanation:

I know this because its a clear obvious answer not only that it was one of my USA TESTPREP questions and it was right.

All you mainly have to do is the math - F=ma , In each case , the acceleration is 5 m/s squared

Think of a way you could demonstrate elastic force to a younger student. Describe the procedure you would follow and the materia
Soloha48 [4]

Answer:

I feel like to demonstrate you would use an elastic band as the material. You obviously have to put force in order to see how far it stretches. From this you can also find about its resistance and durability

Also you have to make sure the distance between the two hands are equal as you want an accurate result.

A truck slows from a velocity of 25 m/s to a stop in 70 m. What was the truck’s acceleration
igomit [66]

v^2-u^2=2 x a x d

25^2-0^2=2 x a x 70

625-0=140 x a

625=140a

a=625/140

a=4.46 m/s^2

im not very sure but i think this is how you do this

What is the vertical acceleration of a paper airplane that is launched horizontally with an initial velocity of 2.3 m/s?
mr_godi [17]

Answer:

<em>The vertical acceleration is -9.81 m/s^2</em>

Explanation:

When a body is projected, the body experiences an acceleration in the vertical axis that is proportional to the acceleration due to gravity of the earth, which is equal to 9.81 m/s^2. In this case, the acceleration acts to stop the vertical motion of the paper plane, and hence is a deceleration, which explains the negative vertical acceleration.
