The change in the kinetic energy of the cart is equal to 50 J and the final velocity is 3.16 m/s.
Kinetic energy can be defined as the energy contained by a moving body due to its motion. The change in the kinetic energy of a moving object whenever the work is done on the object.
The kinetic energy can be measured by using the formula mentioned below:
K.E. = ½mv² where m is mass and v is velocity.
Given, the mass of the cart, m = 10 Kg
The distance moved by cart, d = 5 m
The horizontal force exerted on the cart, F = 10 N
W = F.d = 10 (5) = 50 J
Work = Change in K.E. = ½mv² - ½mu² = ½mv²
50 = ½× 10 ×v²
v² = 10
v = 3.16 m/s
