Answer:
α = 27.9794744° ≈ 28.0 m (nearest tenth)
Step-by-step explanation:
Step 1:
Opposite (O) = 42.5 (the side opposite to the reference angle, α)
Adjacent (A) = 80
Hypotenuse (H) = the longest side opposite to the right angle
2. We are given the adjacent (A) and opposite (O) lengths, we would use TOA. Which is:
Tan α = Opp/Adj
Plug in the values
Tan α = 42.5/80
3. Make α stand alone
α =
4. α = 27.9794744° ≈ 28.0 m (nearest tenth)

Answer: The mass of the object is 10 kg
Step-by-step explanation:
According to Newton's second law of motion, the force applied to an object with mass
is directly proportional to its acceleration
:
(1)
If we isolate :
(2) This means the acceleration of the object varies inversely with its mass
Now, we are given the following data to calculate a constant force using (1):
(3)
(4)
(5)
If we apply this same force calulated in (4) in another object with an acceleration of , its mass
will be:
(6)
(7)
Finding :
This is the mass of the object
