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
What is the multiple choice???
If you dropped a ball from any height, and measured its distance from the ground at any regular interval while it's falling, the graph of that distance versus time would be a graph that curves downward.
-- The ball is falling down. As time goes on, it gets closer and closer to the ground. Its remaining distance from the ground keeps decreasing, so the line on the graph slopes down.
-- The speed of the ball keeps increasing (it accelerates) because of the gravitational force on it. As time goes on, it covers more of the remaining distance during each interval than it did in the previous interval. The downward slope of the graph keeps increasing.

Answer:
8.0 rad/s
Explanation:
I₁ = 1.0 kgm², ω₁ = -20.0 rad/s (clockwise is positive direction)
I₂ = 4.0 kgm², ω₂ = 15.0 rad/s
Angular momentum conservation:
I₁ω₁ + I₂ω₂ = (I₁ + I₂)ω
1.0 x (-20.0) + 4.0 * 15.0 = (1.0 + 4.0)ω
40.0 = 5.0ω
so ω = 8.0 rad/s
