I believe the answer is

Explanation:
I may be incorrect because I used to do this a long time ago but I believe I am correct

<u>Answer</u>:
Effort is the unaltered force. Load is the altered force.
answer is 36
because the formulae of momentum is
mass×velocity
Answer:

First option
Explanation:
<u>Operations with functions
</u>
Given two functions f, g, we can perform a number of operations with them including addition, subtraction, product, division, composition, and many others
.
We have


We are required to find

We simply divide f by g as follows

We know rational functions may have problems if the denominator can be zero for some values of x. We must find out if there are such values and exclude them from the domain of the new-found function. We must ensure

or equivalently

Thus the first option is correct
Note: Since
is always a positive number (for x real), our function does not really have any restriction in its domain
Answer:
The speed of the kid and the skateboard together is 0.723 m/s
Explanation:
Let the mass of the kid be 
Let the mass of the skateboard be 
The initial speed of the skateboard, 
The initial horizontal speed of the boy as he jumps on the skateboard, 
Let the speed of the kid and the skateboard together be v
According to the principle of conservation of momentum:

Substituting the appropriate values into the given equation

36 = 49.8 v
v = 36/49.8
v = 0.723 m/s
