Answer:
a= g sinθ
Explanation:
Given that
Angle ,θ = 15° (from the horizontal)
Lets take the mass of the block = m
The acceleration due to gravity = g
The acceleration of the block = a
When block slide down :
The gravitational force on the block = m g sinθ
By using Newton's second law
F= m a
F=Net force ,a acceleration ,m=mass
m g sinθ = ma
a= g sinθ
Therefore the acceleration of the block will be g sinθ.
