What is the Kinetic Energy of a 5kg object traveling at 10 m/s?
Marat540 [252]

Answer:

KE = 250 kg/m/s

Explanation:

use the formula: KE = 1/2 m (v^2)

KE = 1/2 (5) (10^2)

KE = (2.5) (100)

KE = 250 kg/m/s

How is it possible for two objects to have the same momentum but different velocities give an example
castortr0y [4]
Momentum is
p = mv, where m is the mass and v is the speed.
So, if two objects have the same momentum but different speeds, the must have different masses as well.
v1/v2 = m2/m1
The example is a car and a truck. Car has the mass 1000 kg and velocity 100 m/s, and truck has the mass 5000 kg and velocity 20 m/s. Use the formula above to determine is it true that they have the same momentum:
(100 m/s) / (20 m/s) = (5000 kg) / (1000 kg)
5 = 5
So, the example is correct.
Hope this helps! Good luck!

Two satellites orbit the Earth in circular orbits of the same radius. One satellite is twice as massive as the other. Which stat
loris [4]

To solve this problem it is necessary to apply the concepts related to the orbital velocity of a satellite on earth.

This concept is expressed in the equation,

v = \sqrt{\frac{Gm_E}{r}}

Where,

G = Universal Gravitational constant

m_E = Mass of the Earth

Therefore the ratio of the velocity from two satellites is,

\frac{v_1}{v_2} = \sqrt{\frac{r_2}{r_1}}

The ratio between the two satellites is the same, then

\frac{v_1}{v_2} = \sqrt{\frac{r}{r}}

\frac{v_1}{v_2} = 1

v_1 =v_2

Therefore the correct option is B.
