Activity 2 MASS, SPEED AND MOMENTUM DIRECTION:
Arrange the following animals based on their respective mass, speed and momentum in ascending order. You can get the momentum of the animal by multiplying its mass to its velocity.
a. A 500 kg carabao standing still.
b. A 30 kg dog sprinting at 10.0 m/s.
c. A 0.0008 kg ant travelling at 0.005m/s

Answer:
To arrange the animals in ascending order based on their mass, speed, and momentum, let's calculate the momentum for each animal using the given information:
a. A 500 kg carabao standing still.
Mass = 500 kg
Velocity = 0 m/s
Momentum = Mass * Velocity
= 500 kg * 0 m/s = 0 kg·m/s
b. A 30 kg dog sprinting at 10.0 m/s.
Mass = 30 kg
Velocity = 10.0 m/s
Momentum = Mass * Velocity
= 30 kg * 10.0 m/s = 300 kg·m/s
c. A 0.0008 kg ant traveling at 0.005 m/s.
Mass = 0.0008 kg
Velocity = 0.005 m/s
Momentum = Mass * Velocity
= 0.0008 kg * 0.005 m/s = 0.000004 kg·m/s
Now, let's arrange the animals in ascending order based on momentum:
1. The ant (0.000004 kg·m/s)
2. The carabao (0 kg·m/s since it's standing still)
3. The dog (300 kg·m/s)
Note: The dog has the highest momentum, the carabao has an intermediate value of zero momentum since it's not moving, and the ant has the lowest momentum among the given animals.
