Question 12 of 30 | Section A (MCQ, single correct) | Marks: +4 / −1 | Time on this Q: 2:14
A block of mass 5 kg is placed on a rough horizontal surface (coefficient of kinetic friction μk = 0.3).
A force of 25 N is applied to the block at an angle of 30° above the horizontal.
Find the acceleration of the block. (Take g = 10 m/s²)
sin 30° = 0.5, cos 30° = 0.866
