If the horizontal and vertical components of a force are negative, then that force is acting in between ________.
1
North and East
2
North and West
3
South and West
4
South and East
Official Solution
Correct Option:
(3)
Step 1: Concept
Direction components in a Cartesian coordinate system (East = , West = , North = , South = ). Step 2: Analysis
- Horizontal component is negative West ( ).
- Vertical component is negative South ( ). Step 3: Identification
The force vector lies in the third quadrant ( ). Step 4: Conclusion
Hence, the force is acting between South and West. Final Answer:(C)

A ball is thrown upward at a speed of 28 meter per second. What is the speed of ball one second before reaching maximum height? (Given that meter per second²)}
1
10 meter per second
2
1 meter per second
3
2 meter per second
4
18 meter per second
Official Solution
Correct Option:
(1)
Step 1: Concept
At maximum height, the instantaneous velocity is zero. Step 2: Analysis
We need the speed 1 second before the speed becomes 0. Step 3: Calculation
Using for the final second of the ascent:
Final velocity (at max height) = 0.
.
m/s. Step 4: Conclusion
The speed 1 second before maximum height is 10 m/s. Final Answer:(A)
