v = (-4, -2) and need to find alll vectors of magnitude 4 that are perpindicular to v
Homework Equations
The Attempt at a Solution
I tried
let (x, y) be the vector of interest.
-4x -2y = 0
x^2 + y^2 = 16.
Is this the right track? If so, how do i...

A boulder that weighs 1500 kg is moving 10m/s in a Westerly direction, until it collides with a truck of mass 500kg traveling at 20m/s at a direction S30°W. After the collision the boulder moves away at 5m/s at a direction of S70°W. Find the speed and direction of the truck...
All i have done was sub 2 into a(t) = 6t + ∏cos(2∏ t) but i don't know how that would help me.
acceleration is velocity over time yes?
and velocity is distance over time?
Homework Statement
Hi guys. New here.
Im doing some last minute revision and i have a question I am stuck on.
an objects acceleration a in ms^-1 at time t seconds is shown by
a(t) = 6t + ∏cos(2∏ t), where t ≥ 0
if objects initial velocity is 3ms^-1, find:
a) objects velocity...
