At launch the space shuttle weighs 4.5 million pounds. When it is launched from rest, it takes 8.00 s to reach 162km/h , and at

the end of the first 1.00 min its speed is 1620km/h .
a)
Assuming
the acceleration is constant during each time interval (but not
necessarily the same in both intervals), what distance does the shuttle
travel during the interval from 8.00 s to 1.00 min?

Dist = 162*t + A(accelaration)*t^2/2 = 162*52+(((1620-162)/52)*52^2)/2 =162*52+((1620-162)*52)/2=46332kilometres

*brainlest* An object accelerates from rest with a constant acceleration of 2m/s^2. How far will it have moved after 9s? Equatio
boyakko [2]

Answer: You throw an object upwards from the ground with a velocity of 20m/s and it is subject to a downward

acceleration of 9.8 m/s2. How high does it go?

Given Formula Set up Solution

vi=20 m/s

vf=0 m/s

a=-9.8 m/s2

x=?

vf

2 = vi

2 + 2a x (0 m/s)2= (20 m/s)2 + 2 (-

9.8 m/s2) x

x=20.4 meters

Explanation: i known/ i hoped that helped.

What happens when a spinning ice skater draws in her outstretched arms? Group of answer choices Her moment of inertia increases
kotegsom [21]

Answer:

Her moment of inertia decreases causing her spin to speed up. The physics law behind this phenomenon is the conservation of angular momentum.

Explanation:

<em>Theory</em>

<u>The Law of conservation of angular momentum</u>

The angular momentum of a rotating body or a system remains constant unless it is acted upon by an external unbalance force.

Angular momentum = moment of inertia × angular velocity

The moment of inertia = mass×[perpendicular distance from axis of rotation]²

___________________________________________________________

⇒When skater draws in her outstretched arms the mass distribution get      concentrated towards the axis of rotation so the moment of inertia of the body decrease.

But angular moment should conserve so angular velocity  increases (spin increases)

A team of eight dogs pulls a sled with waxed wood runners on wet snow (mush!). The dogs have average masses of 19.0 kg, and the
liberstina [14]

Answer

given,

number of dog = 8

mass of each dog= 19 Kg

mass of sled = 210 Kg

average force = 185 Nss

a) writing all the horizontal force

   force acting by dog - friction force = (M + 8m) a

   8 F_d - μ m g = (M + 8m) a

assuming coefficient of friction of snow be μ = 0.14

    8 x 185 - 0.14 x 210 x 9.8 = (210 + 8 x 19 ) x a

               a = 3.29 m/s²

b)  the kinetic friction of coefficient is less than static friction

 hence, we can suggest that acceleration of the sled will increase once the sled start to move.

                a > 3.29 m/s²
