Hi Everyone ,
I have a problem with the high pressure pump and also the motor (fresh water) water plant that it have high vibration from? I got a wire that is hanging near the ground.? A position given by:
r = [2.0m+(5.0m/s)t] i + [3.0-(1.0m/s^2)t^2] j,
What is the magnititude of the acceleration of the object at time t=2s? Can a point on the same line be non-collinear if it is outside the plane? What is the range of this function and how do you find it? The function is f(n) = √(4-n^4)?
