In the first 10s of a body’s motion, the velocity changes from 10 m/s to 20m/s. During the next 30s the velocity changes from 20m/s to 50m/s. What is the average acceleration in m/s2?
- a)1
- b)2
- c)3
- d)0.5
Correct answer is option 'A'. Can you explain this answer?

Average acceleration is the total change in velocity by the total change in time. Here, total change in velocity = 50 - 10 = 40m/s, and total change in time = 30 + 10 = 40s. Therefore, average acceleration = 1 m/s2.

In the first 10 seconds of a body, several processes and functions occur. Here are some key events that typically take place:
1. Breath: The respiratory system begins the process of inhaling and exhaling, allowing oxygen to enter the body and carbon dioxide to be expelled.
2. Heartbeat: The heart starts pumping blood throughout the body, ensuring that oxygen and nutrients are delivered to the cells and organs.
3. Brain activity: Nerve cells in the brain start firing, initiating various cognitive processes and controlling the body's functions.
4. Reflexes: The body's reflexes may be triggered, causing an automatic response to certain stimuli, such as pulling the hand away from something hot.
5. Muscle contractions: Different muscles in the body may contract and relax, allowing for movement and maintaining posture.
6. Digestion: If food is present in the digestive system, the process of breaking it down may begin, with enzymes being released to aid in digestion.
7. Temperature regulation: The body works to maintain its internal temperature through processes like sweating or shivering, depending on the circumstances.
These are just a few examples, and the specific events can vary depending on the individual and the situation.
