Answer:
x = 1.63 m
Explanation:
mass (m) = 10 kg
μk = 0.3
velocity (v) = 3.1 m/s
Assuming that most of the computers weight is applied on the belt instantaneously, we can apply the constant acceleration equation below
x =
where a = μk.g , therefore
x = /2μk.g
x = (3.1 x 3.1)/(2 x 0.3 x 9.8)
x = 1.63 m
Answer:
The correct option is;
c. 45°
Explanation:
The given information is that the angle the vector makes with the horizontal = θ
Let the magnitude of the resultant vector = R
The horizontal component of the vector are given as follows;
Rₓ = R × cos(θ)
The vertical component of the vector are given as follows;
= R × sin(θ)
The resultant vector, R, in vector form, R, is the sum of the horizontal and vertical components as follows;
R = R × cos(θ)·i + R × sin(θ)·j
Therefore;
The horizontal and vertical component will be equal when cos(θ) = sin(θ)
Given that tan(θ) = sin(θ)/cos(θ), we have that when cos(θ) = sin(θ), tan(θ) = sin(θ)/cos(θ) = sin(θ)/sin(θ) = 1
tan(θ) = 1,
∴ θ = tan⁻¹(1) = 45°
θ = 45°.
