<u>Answer:</u>
When Anne pushes the wheelbarrow 25 meters the work done is 1120 joules
<u>Solution:</u>
We know 
Anne is pushing the wheelbarrow with a force of 70 N at an angle of 
with the horizontal
So the force of Anne will be 
She pushes the wheelbarrow 25 meter, So D = 25 meters
So, the 
Anne has done total 1120 joules work.
Answer:
D
Step-by-step explanation:
Because they are opposite of each other
Answer:
The polynomial is a quadratic binomial
Step-by-step explanation:
we have
Classify the polynomial
<u>By the number of terms</u>
we know that
A polynomial with two terms is a binomial
<u>By the Degree of a Polynomial</u>
we know that
The degree of a polynomial is calculated by finding the largest exponent in the polynomial
In the given problem the largest exponent is 
so
Is a quadratic equation
therefore
The polynomial is a quadratic binomial
Answer:
x = 28.01t,
y = 10.26t - 4.9t^2 + 2
Step-by-step explanation:
If we are given that an object is thrown with an initial velocity of say, v1 m / s at a height of h meters, at an angle of theta ( θ ), these parametric equations would be in the following format -
x = ( 30 cos 20° )( time ),
y = - 4.9t^2 + ( 30 cos 20° )( time ) + 2
To determine " ( 30 cos 20° )( time ) " you would do the following calculations -
( x = 30 * 0.93... = ( About ) 28.01t
This represents our horizontal distance, respectively the vertical distance should be the following -
y = 30 * 0.34 - 4.9t^2,
( y = ( About ) 10.26t - 4.9t^2 + 2
In other words, our solution should be,
x = 28.01t,
y = 10.26t - 4.9t^2 + 2
<u><em>These are are parametric equations</em></u>
would it be 90 ? because of the big angle
