Final answer:
The average speed of the ladybug is calculated by dividing the total distance traveled by the time taken. The average velocity is the displacement divided by the time taken. Acceleration is the rate of change of velocity. Some measurements, such as distance and time, are scalar quantities, while others, such as velocity, are vector quantities.
Step-by-step explanation:
1. Average Speed:
The average speed of the ladybug can be calculated by dividing the total distance it traveled by the time taken. For example, if a ladybug travels a total distance of 10 meters in 5 seconds, the average speed would be 2 meters per second.
2. Average Velocity:
The average velocity of the ladybug is the displacement divided by the time taken. Displacement is the straight-line distance between the initial and final positions. For instance, if a ladybug starts at position (0,0) and ends at position (5,3) in 10 seconds, the average velocity is (5,3) / 10 = (0.5, 0.3) m/s.
3. Acceleration:
Acceleration is the rate of change of velocity. To calculate acceleration, we divide the change in velocity by the time taken. For example, if a car's velocity changes from 20 m/s to 40 m/s in 5 seconds, the acceleration would be (40 - 20) / 5 = 4 m/s².
4. Average Rocket Acceleration:
To find the average acceleration of the rocket during the initial minute, we divide the change in velocity by the time taken. For instance, if the rocket's velocity changes from 0 m/s to 100 m/s in 60 seconds, the average acceleration would be (100 - 0) / 60 = 1.67 m/s².
