Answer:
Angle of incline is 20.2978Ā°
Explanation:
Given that;
Gravitational acceleration on a planet a = 3.4 m/sĀ²
Gravitational acceleration on Earth g = 9.8 m/sĀ²
Angle of incline = ā
Mass of the stone = m
Force on the stone along the incline will be;
F = mgSinā
F = ma
The stone has the same acceleration as that of the gravitational acceleration on the planet.
so
ma = mgSinā
a = gSinā
Sinā = a / g
we substitute
Sinā = (3.4 m/sĀ²) / (9.8 m/sĀ²)
Sinā = 0.3469
ā = Sinā»Ā¹( 0.3469 )
ā = 20.2978Ā°
Therefore, Angle of incline is 20.2978Ā°
