Answer:
The acceleration of a body moving down a frictionless inclined plane at an angle of 30° = 4.9
Explanation:
As shown n the figure,
Acceleration of a body moving on a frictionless surface = gsinθ
where, g = Acceleration due to gravity= 9.8
and given that inclination of the frictionless surface θ = 30°
So,
Acceleration of a body moving on a frictionless surface = 9.8sin30°
=9.8
=4.9
The correct answer is (a)
