An object is thrown directly up (positive direction) with a velocity (v o ) of 20.0 m/s and d o = 0. How high does it rise (v =

Lelechka [254]

Answer:

h=20.38 m

Explanation:

Given that

Initial speed of object u = 20 m/s

Acceleration $g= 9.8\ \frac{m}{s^2}$

We know that

$v^2=u^2-2gh$

Here acceleration and velocity is in opposite direction so the object will come rest after reaching at distance h.When body will reach at its highest position then velocity will become zero(v=0).

Now by putting the values

$v^2=u^2-2gh$

$0 =20^2-2\times 9.1\times h$

h=20.38 m

A 2.1 ✕ 103-kg car starts from rest at the top of a 5.9-m-long driveway that is inclined at 19° with the horizontal. If an avera

Lina20 [59]

Answer:

3.9 m/s

Explanation:

We are given that

Mass of car,m= $2.1\times 10^3 kg$

Initial velocity,u=0

Distance,s=5.9 m

$\theta=19^{\circ}$

Average friction force,f= $4.0\times 10^3 N$

We have to find the speed of the car at the bottom of the driveway.

Net force, $F_{net}=mgsin\theta-f=2.1\times 10^3\times 9.8sin19-4.0\times 10^3$

Where $g=9.8 m/s^2$

Acceleration, $a=\frac{F_{net}}{m}=\frac{2.1\times 10^3\times 9.8sin19-4.0\times 10^3}{2.1\times 10^3}$

$v=\sqrt{2as}$

$v=\sqrt{2\times \frac{2.1\times 10^3\times 9.8sin19-4.0\times 10^3}{2.1\times 10^3}\times 5.9}$

v=3.9 m/s

What state of matter does sound travel the fastest?

antoniya [11.8K]

Sound travels fastest through matter in the <em>solid state</em>.

I know this from having answered a huge number of Brainly questions that required me to look up things like this:

-- Speed of sound in air . . . about 340 m/s

-- Speed of sound in sea-water . . . about 1,500 m/s

-- Speed of sound in steel . . . about 5,960 m/s

Explain the 8 stages of Erikson’s Psychosocial Development.

Artyom0805 [142]

Answer:

Stage 1: Infancy: Trust vs. Mistrust.

Stage 3: Preschool Years: Initiative vs. Guilt.

Stage 4: Early School Years: Industry vs. Inferiority.

Stage 6: Young Adulthood: Intimacy vs. ...

Stage 7: Middle Adulthood: Generativity vs. ...

Stage 8: Late Adulthood: Ego Integrity vs. ...

The key idea in Erikson's theory is that the individual faces a conflict at each stage, which may or may not be successfully resolved within that stage. For example, he called the first stage 'Trust vs Mistrust'. If the quality of care is good in infancy, the child learns to trust the world to meet her needs.
