A. 10)
B. 100
C. 12 J
D. 120 J

Answer 1

The Kinetic energy of the 6kg cart moving at a speed of 2 m/s at the bottom of the ramp is 12 J

Step-by-step 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,

`K.E= (1)/(2) m v ^2`

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

`= (1)/(2) m v ^2`

`= (1)/(2) (6) (2)^2`

`= (1)/(2) (6)(4)`

`= (1)/(2)* (24)`

`= (24)/(2)`

= 12 J
