A 7-kg mass slides down a smooth incline. The incline makes an angle of 30° with the horizontal. The acceleration of the mass along the incline is
A) 4.9 m/s $2$
B) 8.2 m/s $2$
C) 6.5 m/s $2$
D) 9.1 m/s $2$

Question

Quizplus · Accepted Answer

The acceleration of the mass along the incline can be calculated using the formula $a = g \sin(\theta)$, where $g = 9.8 \, \text{m/s}^2$ is the acceleration due to gravity and $\theta = 30^\circ$ is the angle of the incline. Substituting the given values, $a = 9.8 \sin(30^\circ) = 9.8 \times 0.5 = 4.9 \, \text{m/s}^2$.
