Im pretty sure the answer if elasticity
Answer:
The straight line
Explanation:
All the other stuff is sound waves
Answer:
final speed of the first object: 17.73 cm/s
final speed of the second object: 24.23 cm/s
Explanation:
Data:
mass of the first object, m1 = 27.0 g
mass of the second object, m2 = 11.0 g
initial speed of the first object, v1i = 21.5 cm/s
initial speed of the second object, v2i = 15 cm/s
final speed of the first object, v1f = ? cm/s
final speed of the second object, v2f = ? cm/s
Elastic collisions formula:
v1f = (m1 - m2)/(m1 + m2) * v1i + 2*m2/(m1 + m2) * v2i
v1f = (27 - 11)/(27 + 11) * 21.5 + 2*11/(27 + 11) * 15
v1f = 17.73 cm/s
v2f = 2*m1/(m1 + m2) * v1i + (m2 - m1)/(m1 + m2)*v2i
v2f = 2*27/(27 + 11) * 21.5 + (11 - 27)/(27 + 11)*15
v2f = 24.23 cm/s
Answer:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
Newton's First Law of Motion is also known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
The inertia of an object such as a truck is greatly dependent or influenced by its mass; the higher quantity of matter in a trailer, the greater will be its tendency to continuously remain at rest.
In conclusion, inertia is applicable to all physical objects.
