A 2530-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so that

gavmur [86]

Answer:

A = 1.4 m/s²

B = -0.10493 m/s³

a = 1.29507 m/s²

T = 28095.8271 N

T = 1.13198 W

Explanation:

t = Time taken

g = Acceleration due to gravity = 9.81 m/s²

The equation

$v(t)=At+Bt^2$

Differentiating with respect to time

$\frac{dv}{dt}=\frac{d(At+Bt^2)}{dt}\\\Rightarrow 1.4=A+2Bt$

At t = 0

$1.4=A$

Hence, A = 1.4 m/s²

$B=\frac{v-At}{t^2}\\\Rightarrow B=\frac{2.18-1.4\times 1.8}{1.8^2}\\\Rightarrow B=-0.10493\ m/s^3$

B = -0.10493 m/s³

At t = 5 seconds

$a=1.4+2\times -0.010493\times 5=1.29507\ m/s^2$

a = 1.29507 m/s²

$T=m(a+g)\\\Rightarrow T=2530(1.29507+9.81)\\\Rightarrow T=28095.8271\ N$

T = 28095.8271 N

Weight of rocket

$W=2530\times 9.81=24819.9\ N$

$\frac{T}{W}=\frac{28095.8271}{24819.9}\\\Rightarrow \frac{T}{W}=1.13198\\\Rightarrow T=1.13198W$

T = 1.13198 W

An object travels at constant velocity of 3 m/s for a time period of 7.15 s. What is its displacement over this time?

son4ous [18]

Hi there!

We can use the following equation for constant velocity:

$\large\boxed{d = vt}$

d = displacement (m)

v = velocity (m/s)

t = time (s)

Plug in the givens:

$d = 3 * 7.15 = \boxed{21.45 m}$

How does 1 horsepower compare to 1 watt power

yaroslaw [1]

"Life is wasted if we do not grasp the glory of the cross, cherish it for the treasure that it is, and cleave to it as the highest price of every pleasure and the deepest comfort in every pain. What was once foolishness to us—a crucified God—must become our wisdom and our power and our only boast in this world.” - John Piper

What are the 7 electromagnetic waves in order from lowest to highest wavelength?

ozzi

The electromagnetic spectrum is divided into seven different frequency ranges which are from lowest to highest, radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.

The electromagnetic spectrum includes electromagnetic waves with frequencies between one hertz and above 10²⁵ hertz, or wavelengths between thousands of kilometres and a small portion of the size of an atomic nucleus. The electromagnetic waves found within each of these bands are referred to by a different name. Starting at the low frequency(long wavelength), end of the spectrum, these are radio waves, micro waves, infrared, visible light, ultraviolet, x-rays and gamma rays. This frequency range is divided into separate bands.
