I don’t know, which statement ahh I see white screen lol
Answer:
![\boxed {\boxed {\sf 100,000 \ Joules}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20100%2C000%20%5C%20Joules%7D%7D)
Explanation:
Kinetic energy is energy due to motion. The formula is half the product of mass and velocity squared.
![E_k= \frac{1}{2} mv^2](https://tex.z-dn.net/?f=E_k%3D%20%5Cfrac%7B1%7D%7B2%7D%20mv%5E2)
The mass of the roller coaster car is 2000 kilograms and the car is moving 10 meters per second.
Substitute these values into the formula.
![E_k= \frac{1}{2} (2000 \ kg ) \times (10 \ m/s)^2](https://tex.z-dn.net/?f=E_k%3D%20%5Cfrac%7B1%7D%7B2%7D%20%282000%20%5C%20kg%20%29%20%5Ctimes%20%2810%20%5C%20m%2Fs%29%5E2)
Solve the exponent.
- (10 m/s)²= 10 m/s * 10 m/s= 100 m²/s²
![E_k= \frac{1}{2} (2000 \ kg ) \times (100 \ m^2/s^2)](https://tex.z-dn.net/?f=E_k%3D%20%5Cfrac%7B1%7D%7B2%7D%20%282000%20%5C%20kg%20%29%20%5Ctimes%20%28100%20%5C%20m%5E2%2Fs%5E2%29)
Multiply the first two numbers together.
![E_k= 1000 \ kg \times (100 \ m^2/s^2)](https://tex.z-dn.net/?f=E_k%3D%201000%20%5C%20kg%20%20%5Ctimes%20%28100%20%5C%20m%5E2%2Fs%5E2%29)
Multiply again.
![E_k= 100,000 \ kg*m^2/s^2](https://tex.z-dn.net/?f=E_k%3D%20100%2C000%20%5C%20kg%2Am%5E2%2Fs%5E2)
- 1 kilogram square meter per square second is equal to 1 Joule.
- Our answer of 100,000 kg*m²/s² is equal to 100,000 Joules.
![E_k= 100,000 \ J](https://tex.z-dn.net/?f=E_k%3D%20100%2C000%20%5C%20J)
The roller coaster car has <u>100,000 Joules</u> of kinetic energy.
Answer:
F = 4.147 × 10^23
v = 1.31 × 10^4
Explanation:
Given the following :
mass of Jupiter (m1) = 1.9 × 10^27
Mass of sun (m2) = 1.99 × 10^30
Distance between sun and jupiter (r) = 7.8 × 10^11m
Gravitational force (F) :
(Gm1m2) / r^2
Where ; G = 6.673×10^-11 ( Gravitational constant)
F = [(6.673×10^-11) × (1.9 × 10^27) × (1.99 × 10^30)] / (7.8 × 10^11)^2
F = [25.231 × 10^(-11+27+30)] / (60.84 × 10^22)
F = (25.231 × 10^46) / (60.84 × 10^22)
F = 3.235 × 10^(46 - 22)
F = 0.4147 × 10^24
F = 4.147 × 10^23
Speed of Jupiter (v) :
v = √(Fr) / m1
v = √[(4.147 × 10^23) × (7.8 × 10^11) / (1.9 × 10^27)
v = √32.3466 × 10^(23+11) / 1.9 × 10^27
v = √32.3466× 10^34 / 1.9 × 10^27
v = √17. 023 × 10^34-27
v = √17.023 × 10^7
v = 13047.221
v = 1.31 × 10^4
