Answer:

4 kg at 30 m/s

Explanation:

comparing in pair, the 3rd is more than the 1st, and the 4th is more than the 2nd, so it boils down to the lasts two. calculate, and im pretty sure you get 4 kg at 30 m/s...

Momentum of a ball of mass 2 kg moving at 30 m/s = 2 kg × 30 m/s = 60 kg m/s

Momentum of a ball of mass 3 kg moving at 20 m/s = 3 kg × 20 m/s = 60 kg m/s

Momentum of a ball of mass 4 kg moving at 30 m/s = 4 kg × 30 m/s = 120 kg m/s

Momentum of a ball of mass 5 kg moving at 20 m/s = 5 kg × 20 m/s = 100 kg m/s

So, highest momentum is of a ball of mass 4 kg moving at 30 m/s (120 kg m/s).

he cans have essentially the same size, shape, and mass. Which can has more energy at the bottom of the ramp
stepladder [879]

Answer:

c. both have same energy

Explanation:

The complete question is

suppose you have two cans, one with milk, and the other with refried beans. The cans have essentially the same size, shape, and mass. If you release both cans at the same time, on a downhill ramp, which can has more energy at the bottom of the ramp? ignore friction and air resistance..

a. can with beans

b. can with milk

c. both have same energy

please explain your answer

Since both cans have the same size, shape, and mass, and they are released at the same height above the ramp, they'll possess the same amount of mechanical energy. This is because their mechanical energy, which is the combination of their potential and kinetic energy are both dependent on their mass. Also, having the same physical quantities like their size and shape means that they will experience the same environmental or physical factors, which will be balanced for both.

What happens whenever energy is transformed from one form to another?
andriy [413]

Answer:

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
