Lightbulb is a really good one
Same with the sun. That one has Chemical as well
So, acceleration is the change of velocity in time. If no vectors are used, one can use speed:
a = (final speed - start peed)/ time = 10/5= 1 m/s^2,
Notice that the units are m/s^2, or (m/s)/s. That is speed (m/s) per unit time (s)
Answer:
1.The Washington Monument is 555 feet tall.A.If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters? 1,820.4 mB.A worker assigned to the restoration of the Washington Monument is checking the condition of the stone at the very top of the monument. A nickel with a mass of 0.005 kg is in her shirt pocket. What is the gravitational potential energy (GPE) of the nickel at the top of the monument?GPE = mghGPE = (0.005 kg)(0 m/s2)(1,820.4 m)GPE = 0 JC.What is the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument?KE = 1/2mv2KE = (0.5)(0.005 kg)(0 m/s)2KE = 0 JD.If the nickel accidentally falls out of her pocket, what will happen to the gravitational potential energy (GPE) of the nickel as it falls to the ground?The GPE will decrease because the height is decreasing.E.If the nickel accidentally falls out of her pocket, what will happen to the kinetic energy (KE) of the nickel as it falls to the ground
