Answer:

The 20 kg stone traveling at 10m/s

Explanation:

Hi, the kinetic energy is the energy available of the objects in movement.

That energy can be calculated be the next formula:

ec=0.5*m*v^2

Where:

  • ec is the kinetic energy [J]
  • m is the mass of the object [kg]
  • v is the velocity of the object [m/s]

Case A:

ec=0.5*20kg*(10m/s)^2

ec=1000 J

Case B:

ec=0.5*40kg*(4m/s)^2

ec=320 J

Case C:

ec=0.5*30kg*(6m/s)^2

ec=540 J

Case D:

ec=0.5*50kg*(2m/s)^2

ec=100 J

Answer: A 20kg Stone traveling an 10 m/s

Explanation:

The Formula for Kinetic Energy is KE = 0.5 x mv², using this equation you can then find the item with the most Kinetic Energy in Joules (J) 0.5 x 20 x 10 = 200 Joules.

  • A)Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s)

  • 2KBr(aq)+BaI2(aq) → 2KI(aq)+BaBr2(s)

  • B)Balance the Chemical Equation for the reaction of calcium carbonate with hydrochloric acid: 
  • CaCO3+ HCl -> CaCl2 + CO2 + H2O To balance chemical equations we need to look at each element individually on both sides of the equation. calcium carbonate is a chemical compound with the formula CaCO3.
