Answer:
Energy increased by 4 times.
Explanation:
Energy=1/2mv2
=1/2m (l/t)2
Where m is mass, l is length and t is time.
Mass, length and time increase 4 times
1/2 Will remain constant so we ignore it
Energy= (4m×4l×4l)/(4t×4t)
=4m×16(lsquare)/16(tsquare)
=4 × m(lsquare)/(tsquare)
Energy increased by 4 times.
