Question

what is the kinetic energy of a 2000 kg boat moving at 5 metre per second?​

Answer 1

Answer:

25000 J  or  25 k J

Explanation:

KE=1/2 mv²

kinetic energy = 1/2 *mass* velocity ²

where mass is in kilograms  k g

and velocity is in metres per second  m / s .

here, m=2000

v=5

v²=25

1/2mv² = 1/2 · 2000 · 25

=50000/2

=25000

KE = 25000 J  or  25 k J
