1. A ball is thrown vertically upward with a velocity of 20 m/s. How long will it take to reach the highest point?
(a) 1 s
(b) 2 s
(c) 4 s
(d) 5 s

🟩 Correct Answer: (b) 2 s

📘 Explanation:
At the highest point, final velocity = 0.
Use the first equation of motion:
𝑣
=

​
≈2.04 s
So, the nearest option is 2 seconds.

2. A car starts from rest and accelerates uniformly at 4 m/s². What is the distance covered in 5 seconds?
(a) 25 m
(b) 50 m
(c) 100 m
(d) 125 m

🟩 Correct Answer: (c) 100 m

Acceleration has magnitude and direction, so it's a vector.

5. What is the SI unit of power?
(a) Joule
(b) Watt
(c) Newton
(d) Volt

🟩 Correct Answer: (b) Watt

📘 Explanation:

Power is the rate of doing work.

SI unit: Watt
