Explanation:

We know that the overall mechanical energy of a device stabilizes in the absence of any external force. We know that that the total of potential and kinetic of the freely velocity vector remains same. ,So mechanical energy of a body, underneath gravitation, remains constant.

Answer:

30m/s

Explanation:

Given parameters:

Distance  = 12m

Time taken  = 0.4s

Unknown:

Velocity of the tennis ball = ?

Solution:

Velocity of a body is the displacement per unit of time.

  Velocity  = [tex]\frac{displacement}{time}[/tex]  

So;

      Velocity  = [tex]\frac{12}{0.4}[/tex]   = 30m/s

Answer:

12 joules

Explanation:

I'm assuming you're looking for kinetic energy?? Kinetic energy is 1/2 mv^2. 4 squared is 16, 16 times 1.5 = 24. 24/2 = 12.
