Question

A 4 kg bird is flying and it has a total kinetic energy of 32 Joules. What is the bird's current velocity?

Answer 1

Answer:

K = 32 J

 

Explanation:

Kinetic energy is given by:

K = 1 2 m v 2  

We are given that  m = 4 k g  and  v = 4 m s .

⇒ K = 1 2 ( 4 k g ) ( 4 m s ) 2  

= 32 N m

= 32 J
