Answer:
The Kinetic energy of the 6kg cart moving at a speed of 2 m/s at the bottom of the ramp is 12 J
Explanation:
Given:
Mass of the cart = 6 kg
Speed with which the cart is moving = 2 m/s
To Find:
The Kinetic Energy = ?
Solution:
The Kinetic Energy of the object is given,
[tex]K.E= \frac{1}{2} m v ^2[/tex]
where
m is the mass of the object
v is the velocity of the object
Now substituting the given values
The Kinetic energy of the 6kg cart moving at a speed of 2 m/s is
[tex]= \frac{1}{2} m v ^2[/tex]
[tex]= \frac{1}{2} (6) (2)^2[/tex]
[tex]= \frac{1}{2} (6)(4)[/tex]
[tex]= \frac{1}{2}\times (24)[/tex]
[tex]= \frac{24}{2}[/tex]
= 12 J
