Question

A body of mass 2kg falling from a height of
18m what will be its kinetic energy when at
5 meters above the
ground?
​

Answer 1

Answer:

260 joules

Explanation:

m=2kg

u=0

s=13m

v=?

g=  10 m/s^2

v^2= u^2+ 2gs

v^2= 0+ 2(10)(13)

v^2= 260

v= root 260

K.E. = 1/2 mv^2

K.E.= 1/2(2)(260)

K.E.= 260 joules

Hope it satisfies your need.
