Approximately

#### Explanation:

Kinetic energy is expressed through the equation,

#m# is the mass of the object in kilograms

#v# is the velocity of the object in meters per second

So, we plug in the values into the given equation, and we get

I retained answer in fractions as the velocity is given in fractions.

#### Explanation:

Kinetic energy is given by the expression for a body of mass

#KE=1/2mv^2#

Inserting given values we get

#KE=1/2xx9xx(5/4)^2#

#KE=225/32#

#KE=7 1/32\ J#
