Understanding the Problem
When a ball is thrown vertically upwards, it will eventually stop rising due to the force of gravity acting against its motion. The problem asks for the velocity of the ball after 2 seconds of being thrown upwards with an initial velocity of 20 m/s.
Key Concepts
- Initial Velocity (u): 20 m/s (upwards)
- Acceleration due to Gravity (g): -10 m/s² (downwards)
- Time (t): 2 seconds
Velocity Calculation
To find the velocity after 2 seconds, we can use the formula:
- Final Velocity (v) = u + (g * t)
Plugging in the values:
- u = 20 m/s
- g = -10 m/s²
- t = 2 s
Now, substituting these into the formula:
- v = 20 + (-10 * 2)
Calculating further:
- v = 20 - 20
- v = 0 m/s
Conclusion
After 2 seconds, the ball reaches its highest point and its velocity becomes 0 m/s. Therefore, the answer is:
- Correct Answer: a) 0 m/s
This means that at the 2-second mark, the ball has stopped moving upwards and is at the peak of its trajectory. It will then start to fall back down due to gravity.

Since, force on the vehicle is constant, it will move with a constant acceleration. For particle starting from rest, velocity, v = at
∴ Graph of E versus t will be parabola of increasing slope. Thus, graph (iv) is correct.
Power associated with force is equal to, P = Fv = Fat Thus, graph of P versus t will be a straight line. Hence, graph (i) is correct. And graphs (ii) and (iii) are incorrect.

(I) T and V will combine to form TV2 type compound as shown:
(II) T and U will form cations as they have 2 and 3 valence electrons respectively and can easily lose these electrons to form cations. On the other hand, V and W will form anions by accepting 1 and 2 electrons respectively in their outermost shell to attain a stable octet. (III) U and V combine to form UV3 type compound as shown:

I - Change 1 requires an increase in temperature and a decrease in pressure, and is also known as sublimation. During sublimation, solid state is directly converted to gaseous state without coming into liquid state.
II - Change 3 depicts the conversion of gaseous state to liquid state or liquefaction of gas. Gases can be liquefied by applying pressure and reducing temperature.
