Question

What is the kinetic energy of a 2000kg boat moving at 5m/s?

Answer 1

25000 J or 25 kJ

Step-by-step explanation:

K = 1/2 mv^2

where mass is in kilograms kg

and velocity is in metres per seconds m/s

Here, m = 2000, v = 5

v^2 = 5*5 = 25

1/2 mv^2 = 1/2 * 2000 * 25

= 50000/2

= 25000

Hope it helps!
