Question

How fast a girl of 35kg run so thather kinetic energy becomes 700 joule

Answer 1

as we know kinetic energy = 1/2 mv^2
700 = 1/2 ×35×v^2
1400/35 = v^2
√40 = v
so v = √40 m/sec
HOPE THIS HELPS YOU

Answer 2

Answer:

As we know kinetic energy = 1/2 mv^2

700 = 1/2 ×35×v^2

1400/35 = v^2

√40 = v

So v = √40 m/sec
