92% just divide the numerator by the denominator
The option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".
<h3>What is mass?</h3>
A tangible body's mass is the amount of matter it possesses. It's also a metric of inertial, or the resistance to velocity when a net force is exerted.
The question is incomplete.
The complete question is:
A box that has a mass of 80 kg slides down a ramp with a 30-degree angle. The free-body diagram shows the forces acting on the box. Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth?
-0.5 m/s²
-4.9 m/s²
-8.5 m/s²
-9.8 m/s²
First we calculate the weight:
W = mg = 80×9.8
W = 784 N
The weight component parallel to the ramp is:
W₁ = Wsin30
W₁ = (784)(sin30)
W₁ = 392 N
From the Newton's second law:
a = F/m
a = 392/80
a = 4.9 m/s²
Thus, the option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".

4 of you divide 6 by 1.25 it's 4.8 but for a whole bows it's 4
Answer:
hope it will help u in understanding
Answer:
5, 9
Step-by-step explanation:
To obtain the next term in a sequence add the common difference d to the previous term.
d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4
Thus
a₄ = a₃ + 4 = 1 + 4 = 5
a₅ = a₄ + 4 = 5 + 4 = 9
