How much work does it take to accelerate from 5 m/s to 10 m/s?

Physics
1 answer:
REY [17]2 years ago
3 0

Answer:

KE (5) = 1/2 M V^2 = 25/2 M

KE (10) = 1/2 M V^2 = 100/2 M

KE (10) - KE (5) = M/2 (100 - 25) = 75/2 / M

An object traveling at 10 m/s has 4 times the kinetic energy as an object traveling at 5 m/s

Total work would depend on the mass being accelerated

A pilot in an airplane flying at 25,000 ft sees two towns directly ahead of her in a straight line. The angles of the depression
insens350 [35]

Answer:

The towns are 32,635 ft apart.

Explanation:

From the image drawn below:

AB = x ft

BC = a ft

AC = (x + a) ft

Considering triangle PCB,

tan 50° = 25000 / a

Or,

a = 25000 / tan 50°

Since tan x = 1/ cot x

a = 25000×cot 50°------------------------------------1

Considering triangle PCA,

tan 25° = 25000 / (a + x)

Or,

a + x = 25000 / tan 25°

Since tan x = 1/ cot x

a + x = 25000×cot 25° -------------------------------2

Thus, finding x from equation 1 and 2, we get:

x = 25000 (cot 25° - cot 50°)

Using cot 25° = 2.1445 and cot 50° = 0.8394, we get:

<u>x ≈ 32,635 ft</u>

<u>Thus, the distance between two towns is 32,635 ft.</u>

The moon has a mass of 7.34 . 102 kg and a radius of 1.74 . 106 meters. If you have a mass of 66 kg,
Ierofanga [76]

Answer:

F=1.06\times 10^{-18}\ N

Explanation:

Given that,

Mass of the Moon, M=7.34\times 10^2\ kg

Mass of the person, m = 66 kg

The radius of Moon, r=1.74\times 10^6\ m

We need to find the force between the person and the Moon. The formula for the gravitational force is given by :

F=G\dfrac{Mm}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{7.34\times 10^2\times 66}{(1.74\times 10^6)^2}\\\\=1.06\times 10^{-18}\ N

So, the required force is 1.06\times 10^{-18}\ N.

Calculate the force it would take to accelerate a 250 kg motorcycle at a rate of 5 m/s2
Sphinxa [80]

Force = mass x acceleration

Mass is given to be 250kg

Acceleration is given to be 5m/s^2

Force = 250kg x 5m/s^2 = 1,250 kgm/s^2 = 1,250 Newtons
