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
=
300
kg
⋅
m s
−
2
⋅
20
m
⇒
W
=
300
⋅
20
kg
⋅

⇒
W
=
6000
kg
⋅

∴
W
=
6000
J
The gain in kinetic energy 
E
K
 is the same amount as the work done moving the cart:
∴
E
K
=
6000
