Complete Question
A student bikes to school by traveling first dN = 0.900 miles north, then dW = 0.300 miles west, and finally dS = 0.100 miles south.
Similarly, let d⃗ W be the displacement vector corresponding to the second leg of the student's trip. Express d⃗ W in component form.
Express your answer as two numbers separated by a comma. Be careful with your signs.
Answer:
The value is
Explanation:
From the question we are told that
The first displacement is i.e positive y-axis
The second displacement is i.e negative x-axis
The final displacement is i.e negative y-axis
Generally dW in component for is
Generally the total displacement of the student is mathematically represented as
Answer: 125/24 N
Explanation:
The work can be calculated with W = Fs
Where W = work
F = force
and s = displacement
Let's set up the equation:
500w = F * 96m
= 125/24 or roughly 5.2 N of force
The concept required to solve this problem is hydrostatic pressure. From the theory and assuming that the density of water on that planet is equal to that of the earth we can mathematically define the pressure as
Where,
= Density
h = Height
g = Gravitational acceleration
Rearranging the equation based on gravity
The mathematical problem gives us values such as:
Replacing we have,
Therefore the gravitational acceleration on the planet's surface is
Answer:
If an object accelerates from rest, with a constant acceleration of 5.4 m/s2, what will its velocity be after 28s? v0 = 0 v= ? a = 5.4 m/s2. ∆x = t = 28 s. 3.
