Question

A 2000 kg boat drifts along the waves at a velocity of 3 m/s. What is

the kinetic energy of the boat?

Select one:

18,000 J

6000 J

OJ

9000 J

Answer 1

K = 9000 J

Step-by-step explanation:

Given that,

The mass of a boat, m = 2000 kg

The velocity of the boat, v = 3 m/s

We need to find the kinetic energy of the boat. We know that the kinetic energy of an object is given by :

`K=(1)/(2)mv^2\\\\K=(1)/(2)* 2000* 3^2\\\\K=9000\ J`

So, the required kinetic energy is equal to 9000 J.
