How did earths moon form?

Goshia [24]

Earths moon is said to be formed way back when the earth was still a molten ball of lava. Something huge crashed into it, causing a piece to fly off. Due to earths gravity, the piece cooled and began orbiting us.

A boy drops a coin down a well that is 225 m deep. How long does it take the coin to hit the bottom of the well? please help

Nady [450]

<span>It takes 6.78 seconds for the coin to hit the bottom of the well. We can use the equation h = 0.5gt^2, where h is the height of the coin, g is the gravitational constant of 9.8m/s^2, and t is the time is takes for the coin to hit the bottom of the well. Solve for t to obtain 6.87 seconds.</span>

Huck Finn walks at a speed of 0.70 m/s across his raft (that is, he walks perpendicular to the raft’s motion relative to the sho

ZanzabumX [31]

Answer

given,

Hunk Finn speed,v_y= 0.7 m/s

Speed of river,v_x = 1.50 m/s

Assuming the speed of the river is in x-direction.

Speed of Hunk Finn to be in y-direction.

Hunk velocity relative to river =

$x = \sqrt{v_y^2+v_x^2}$

$x = \sqrt{2.74}$

$x =1.66\ m/s$

Speed of Hunk relative to river = 1.66 m/s

direction of the boat

$\theta =tan^{-1}(\dfrac{v_y}{v_x})$

$\theta =tan^{-1}(\dfrac{0.7}{1.50})$

$\theta = 25.01^{\circ}$

Hence, angle of the raft is 24.01°

A car travelling at 5.0 m/s starts to speed up. After 3.0 s its velocity has increased to 11 m/s. a) What is its acceleration? (

lions [1.4K]

initially, the car is traveling at 5.0 m/s.

so, we know acceleration for changing velocity is :

a = (v-v $_{o}$ )/t ..........(i)

where v is the final velocity

v $_{o}$ is the initial velocity

t is the time taken to change velocity

Now, as per the question :

initial velocity, v $_{o}$ =5.0 m/s

final velocity, v =11 m/s

time taken, t = 3 s

putting the values in equation (i),

a = ( 11-5 )/3

a = 2 m/s²

Therefore, a, after 3 s, is <em>2 m/s².</em>
