Explanation:
Mass of truck
Velocity of truck
Mass of car
let be the car velocity and u be the velocity of combined system after collision at angle of
Conserving momentum in east and North direction Respectively
In east Direction
-------1
In North direction
---------2
Divide 1 and 2 we get
Answer:
- 2.425 x 10^5 J
Explanation:
The gravitational potential energy between earth and the bock is given by
Where, G is the universal gravitational constant = 6.67 x 10^-11 Nm^2/kg^2
M is the mass of earth = 5.8 x 10^24 kg
m is the mass of block = 4 kg
r be the radius of earth = 6380 km = 6380 x 10^3 m
by substituting the values in the above expression, we get
U = - 2.425 x 10^5 J
The answer to your question is in fact <u>True</u>
Why?
Sound waves can only travel through things like water, walls, and solids. so sound cannot travel through space because there is no matter for the vibrations of the sound to work in.
