Identify whether the following force problems are 1D or 2D: a) The engine of a boat pushes it east and the river current pushes the boat north. What is the net force on the boat? b) A parachute pulls straight up on a person and their weight pulls straight down. What is the net force on the person?
Homework Answers
(a) The engine of a boat pushes it east and the river current pushes the boat north.
What is the net force on the boat?
According to an above figure, we have
Fnet = Fx2
+ Fy2
where, Fx = horizontal force on the boat
Fy = vertical force on the boat
(b) A parachute pulls straight up on a person and their weight pulls straight down.
What is the net force on a person?
In a vertical direction, we have
Fy = 0 ; Fnet - w = 0
We know that, weight of a person (w) = m g
Then, we get
Fnet = m g
where, m = mass of a person
g = acceleration due to gravity

QUESTION 3 : Relative motion and 2d vectors
Question 3 (relative motion & 2d vectors) There are two ports, A and B. The displacement from port A to port B is 1600 m at 40% (or 40% north of east). You have a boat that travels 400 meters per minute in the water. Further, there is a constant current in the water that flows 80 meters per minute at 110% (or 20° west of north) as observed from the shore....

Question: When an object is pushed several ways at once, what is the net effect? In mechanics, we think of "force" as a push or a pull. A scientific definition will be discussed later in lecture, and the effects that forces produce on motion will be a major topic of this course. The unit of force in the SI system is the Newton (abbreviation N). For purposes of this exercise, we will be concerned with the way that different forces...

The size of the magnetic force on a straight wire of length
L carrying current I in a uniform magnetic field
with strength B is
F=ILBsin(?).
Here ? is the angle between the direction of the
current (along the wire) and the direction of the magnetic field.
Hence Bsin(?) refers to the component of the
magnetic field that is perpendicular to the wire, B?. Thus
this equation can also be written as
F=ILB?.
