Answer ⇒The acceleration in parallel direction is 2.5 m/s².
Explanation ⇒ Gravitational acceleration made an angle of 15° with the horizontal and we need to find the component of its acceleration in parallel direction.
∴ Angle which acceleration make with parallel = 90 - 15
= 75°
Thus, Using the concept of composition of Vectors,
Acceleration in parallel direction = net acceleration × Cos75
Thus, Acceleration in parallel direction = 9.8 × 0.25
Thus, Acceleration in parallel direction = 2.5 m/s²
Hence, the acceleration in parallel direction is 2.5 m/s².
Hope it helps.
