The Box's Acceleration : g sin θ
<h3>Further explanation </h3>Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
We plot the forces acting on the block (picture attached) according to the y-axis and the x-axis.
Because the motion of the block is in the same direction as the x-axis, ignoring the friction force with the inclined plane, then
Answer:
Explanation:
To solve this problem we use the formula for accelerated motion:
We will take the initial position as our reference () and the downward direction as positive. Since the rock departs from rest we have:
Which means our acceleration would be:
Using our values:
