❂ <u>Weight of block A</u> :
➝ mg sin30° = 18
➝ W (1/2) = 18
➝ W = 18×2
➝ <u>W = 36N </u>
❂ <u>Weight of block B</u> :
➝ N sin30° = 18
➝ (Mg cos30°) sin30° = 18
➝ W' (√3/2)(1/2) = 18
➝ W' (√3/4) = 18
➝ W' = 72/√3
➝ <u>W' = 41.61N</u>
Magnitude of acceleration = (change of speed) / (time for the change)
Change of speed = (speed at the end) - (speed at the start)
Change of speed = (18 m/s) - (0 m/s) = 18 m/s
Time for the change = 22 sec
Magnitude of acceleration = (18 m/s) / (22 sec)
<em>Magnitude of acceleration = 0.818 m/s²</em>
Answer:
- The size of a force
- The perpendicular distance from the pivot the line of action of force
Explanation:
Factors that affect the moment of a force are;
- The size of a force
- The perpendicular distance from the pivot the line of action of force
The magnitude of force applied is directly proportional to the moment of force in that for a perpendicular distance d, increased in force applied will result to a higher moment of force. When the perpendicular distance from the pivot is decreased while the force applied remains constant, the moment of force decreases.
