Answer:
Explanation:
mass of first marble
Initial velocity of the first marble
considering right side as positive
Mass of second marble
After collision first marble moves to the left with a velocity of 18 cm/s
i.e.
considering be the velocity of second marble after collision
The Coefficient of restitution is 1 for an elastic collision
Putting values
So, the velocity of the second marble is 22.5 m/s to the right after the collision
(b)Initial kinetic energy =
Final kinetic energy=
Initial launch velocity, u = 0
Acceleration, a = 300 m/s²
Duration, t = 8.0 s
The distance traveled is
h = ut + (1/2)*a*t²
= (0 m/s)*(8 s) + 0.5*(300 m/s²)*(8 s)²
= 9600 m
Answer: 9600 m
Answer:
It can be either a moon or a satellite
Explanation:
a moon is a piece of space debris that orbits a planetdue to the planets gravitational force. Inherently, satellite mimics a moon but it is used for collecting data and etc
Answer:
Newtons first law of motion: Objects in motion stay in motion unless acted upon by an external force.
