Hello!
To answer your question, salt is a compound!
It is the product of the chemical bond between Na (Sodium) and Cl (Chloride),
Hopes this help you with your question.
Answer: 20 m/s
Explanation:
P = mv
since we're trying to find the velocity, you change the formula to v = P/m
v = ?
P = 9 kgm/s
m = 0.45 kg
v = 9 kgm/s / 0.45kg = 20 m/s
We will use two definitions to solve this problem. The first will be given by the conservation of energy, whereby the change in kinetic energy must be equivalent to work. At the same time, work can be defined as the product between the force by the distance traveled. By matching these two expressions and clearing for the Force we can find the desired variable.


Thus the force acting on the sled is,

Replacing,


Therefore the Force acting on the sled is 32N
