Answer:
θ=12.7°
Explanation:
Lets take the mass of the ball = m
The acceleration due to gravity = g = 9.81 m/s²
The acceleration of the block = a
a= 2.2 m/s²
Lets take angle of incline surface = θ
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
Now by putting the values in the above equation
2.2 = 9.81 sinθ
[tex]sin\theta =\dfrac{2.2}{9.81}\\sin\theta=0.22\\\theta = 12.7\ degrees[/tex]
θ=12.7°
