Answer:
The acceleration of the cart is 1.0 m\s^2 in the negative direction.
Explanation:
Using the equation of motion:
Vf^2 = Vi^2 + 2*a*x
2*a*x = Vf^2 - Vi^2
a = (Vf^2 - Vi^2)/ 2*x
Where Vf is the final velocity of the cart, Vi is the initial velocity of the cart, a the acceleration of the cart and x the displacement of the cart.
Let x = Xf -Xi
Where Xf is the final position of the cart and Xi the initial position of the cart.
x = 12.5 - 0
x = 12.5
The cart comes to a stop before changing direction
Vf = 0 m/s
a = (0^2 - 5^2)/ 2*12.5
a = - 1 m/s^2
The cart is decelerating
Therefore the acceleration of the cart is 1.0 m\s^2 in the negative direction.
Answer:
$28200
Explanation:
Since 1 year has 12 months, 10 years have 120 months.
If one has to pay $235 a month, in 120 months one has to pay $235 done 120 times, which is the product of both numbers:

Explanation:
The Second or the Entropy law of thermodynamics states that every time energy is transformed from one form to another, some of that energy is converted to heat. That means there is never 100% conversion of one form of usable energy to another. Because Heat is not available to do work , the usable amount of energy is wasted each time an energy conversion occurs.
