The velocity of the cart at the bottom of the track is equal to 6.32 m/s.
Kinetic energy can be described as the energy exhibited by a moving body due to its motion. Work will be done by an object in order to change its kinetic energy.
The kinetic energy of a moving body can be determined from the mathematical formula mentioned below:
K.E. = ½mv² where ‘v’ and 'm' are the velocity and mass of the object.
Potential Energy can be defined as the stored energy due to its position and is given by P.E = m×g×h where g, m, and h are the gravitational acceleration, mass, and height.
Given, the mass of the cart =, m= 0.250 Kg
The final velocity of the cart, v = 0
The work done = Change in KE = 5.00 J
½mv² - ½mu² = 5.00
½mu² = 5
(1/2)× 0.25 ×(u)² = 5
u² = 40
u = 6.32 m/s
