Explanation:
In an elastic collision, two or more bodies are in contact with one another and there is no net loss of kinetic energy in the system. By the virtue of this, the bodies and objects do not stick together after they collide.
Both momentum and kinetic energy are conserved in an elastic collision. An example is when a football hits a wall.
For an inelastic collision, the bodies sticks together after they collide and there is a loss of kinetic energy after they collide. An example of this type of collision is when a gum is throw against a wall.
Answer:
18.65
Explanation:
To solve, divide 1865 by 100
1865/100= 18.65
Hope this helps! :) If correct pls mark brainliest :)
You awser is c to the question
Answer:
(a) 19.25 N-m
(b) 25.67 N-m
(c) 0 N-m
Explanation:
Given:
Length of the pedal arm (L) = 0.177 m
Downward force 
= 145 N
Magnitude of torque is given by the formula:
Where, 
(a)
Given:
°
Therefore, torque is given as:
Therefore, the torque is 19.25 N-m.
(b)
Given:
°
Therefore, torque is given as:
Therefore, the torque is 25.67 N-m.
(c)
Given:
°
Therefore, torque is given as:
Therefore, the torque is 0 N-m.
Matter is made of the particles are called atoms!
hope this helps!
