Answer:
m1 = the mass of the blue sphere = 5.8 kg
m2 = the mass of the red sphere = 2.5 kg
v1 = initial velocity of the blue sphere before the collision = 4.1 m/s
v2 = initial velocity of the red sphere before the collision = 0 m/s
v'1 = final velocity of the blue sphere after the collision = 1.3 m/s
v'2 = final velocity of the red sphere after the collision = ?
using conservation of momentum
m1v1 + m2v2 = m1v'1 + m2v'2
(5.8) (4.1) + (2.5) (0) = (5.8) (1.3) + (2.5) (v'2)
23.78 = 7.54 + (2.5) (v'2)
-7.54 -7.54
16.24 = (2.5) v'2
--------- -----------
2.5 2.5
v'2 = 6.5

Absorption occurs when <span>all of the energy from light waves is transferred to a medium! </span>
Answer:
gravitational pull by earth and friction
Explanation:
When the ball is placed on tilted tale it starts rolling because of the force of gravity pulls it downward along the plane of table and frictional force produces torque which generate rotational motion as a result body will start rolling.
Push of the table will be used to generate frictional force f=μ.N
At a speed of 0. 93 ccc, a spaceship travels to a star that is 8. 5 ly distant part and according to a scientist on earth 2.3 years the trip takes.
Spacecraft
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
Satellites, rovers, and space stations are collectively referred to as spacecraft. In science fiction, a big, manned spacecraft that is not a satellite is commonly referred to as a spaceship.
