Work done on cart
:
W
=
6000
J
Kinetic energy of cart
:
E
K
=
6000
J
Explanation:
Work done
W
is defined as the product of force
F
and distance
s
:
⇒
W
=
F
⋅
s
Let's substitute the values of
F
and
s
into the equation:
⇒
W
=
300
N
⋅
20
m
⇒
W
=

∴
W

J
The gain in kinetic energy
E
K
is the same amount as the work done moving the cart:
∴
E
K
=
6000
Answer:
203 YD
Step-by-step explanation:
1.05*prevous month total or
Starting balance * 1.05^n where n is the number of months
To get a you have to have a on its own side
56a=7/4
divide 56 on both sides
a=56/1 divided by 4/7 (switch 7/4 to 4/7 because you are going from division to multiplication)
a=32
Hope this helped
