A 10000 kg rocket blasts off vertically from the launch pad with a constant upward of 2.25 m/s2 and feels no appreciable air res

Sloan [31]

Answer:

The maximum height that the rocket reaches is 645.5 m.

Explanation:

Given that,

Mass = 10000 kg

Acceleration = 2.25 m/s²

Distance = 525 m

We need to calculate the velocity

Using equation of motion

$v^2=u^2+2as$

Put the value in the equation

$v^2=0+2\time2.25\times525$

$v=\sqrt{2\times2.25\times525}$

$v=48.60\ m/s$

We need to calculate the maximum height with initial velocity

Using equation of motion

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

$h=\dfrac{v^2-u^2}{-2g}$

Put the value in the equation

$h=\dfrac{0-(48.60)^2}{-2\times9.8}$

$h=120.50\ m$

The total height reached by the rocket is

$h'=s+h$

$h'=525+120.50$

$h'=645.5\ m$

Hence, The maximum height that the rocket reaches is 645.5 m.

The brightest star in the night sky in the northern hemisphere is Sirius. Its distance from Earth is estimated to be 8.7 light y

katen-ka-za [31]

Answer: $5.11(10)^{13}miles$

Explanation:

A light year is a unit of length and is defined as "the distance a photon would travel in vacuum during a Julian year at the speed of light at an infinite distance from any gravitational field or magnetic field. "

In other words: It is the distance that the light travels in a year.

This unit is equivalent to $5.879(10)^{12}miles$ , which mathematically is expressed as:

$1Ly=5.879(10)^{12}miles$

Doing the conversion:

$8,7Ly.\frac{5.879(10)^{12}miles}{1Ly}=5.11(10)^{13}miles$ This is the distance from Earth to Sirius in miles.
