° incline with constant acceleration. Determine the magnitude of the acceleration of the block.
To solve this problem, we can use the equations of motion for objects moving down an inclined plane. The acceleration of the block can be found using the following equation:
a = g sinθ - μk g cosθ
where g is the acceleration due to gravity (9.81 m/s^2), θ is the angle of the incline (30°), μk is the coefficient of kinetic friction between the block and the incline (which we will assume is zero since there is no mention of friction in the problem), and a is the acceleration of the block.
Plugging in the values, we get:
a = (9.81 m/s^2) sin(30°) - 0
a = 4.90 m/s^2
Therefore, the magnitude of the acceleration of the block is 4.90 m/s^2.
