A 10 kg penguin with an initial velocity of 6.0 m/s toward the
east runs onto a large area of level, frictionless ice. As the
penguin slides across the ice, it is pushed by the wind with a
force that is constant in magnitude and direction. The figure shows
the position of the penguin, at 1.0 s intervals, as it slides on
the ice; the positive direction of the x axis is toward
the east. The penguin first makes contact with the ice at
t = 0. What are the (a) magnitude and
(b) direction of the force of the wind on the
penguin? Give the direction as a positive (counterclockwise) angle
from the +x axis.

Here is the work I did. I got
the angle correct, but can not seem to get the magnitude right.
Thanks

A 321-kg boat is sailing 10.0° north of east at a speed of 2.00 m/s. 30.0 s later, it is sailing 33.0° north of east at a speed of 4.10 m/s. During this time, three forces act on the boat: a 32.3-N force directed 10.0° north of east (due to an auxiliary engine), a 23.9-N force directed 10.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...
A skateboarder travels on a horizontal surface with an initial velocity of 3.8 m/s toward the south and a constant acceleration of 2.1 m/s2 toward the east.

DIFFERENTIAL EQUATION PROBLEM
An object with a mass of 2 kg moves along the x-axis and we will
assume that the positive direction of movement is to the right.
Only one force (in N) is present and opposes the movement. Let
be the speed of the object (in m / s) at time t. The object starts
from the origin (x = 0) with an initial speed of 75 m / s. Suppose
that the resistance force has a magnitude...
2. A very long, straight wire runs from west to east. The wire is 17 m long and carries a 2.6 A current that moves from west to east. a. Earth's magnetic field is approximately uniform, and is directed from south to north. At the location of the wire, the magnetic field has the strength 4.4 x 10-5 T. Calculate the magnitude and direction of the force that Earth's magnetic field applies to the wire. b. What is the magnitude...
A 2-kg ball is thrown up vertically from the ground with initial speed of 9.8 m/s. When it lands on the ground, it is deflected 10 m East from the launching position due to drag by wind toward East. What is the magnitude of the drag? Ignore drag in the vertical direction. This is Question Verbatim. The only hint we were given is that the 10m deflection is extremely important to solving this. I have no idea where to start...
Problem 23.29 (Multistep)
An accelerated electron
An electron is initially at rest. At time t1=0 it is accelerated
upward with an acceleration of a= 1 × 1019
m/s2 for a very short time (this large acceleration is
possible because the electron has a very small mass). We make
observations at location A, x= 16 meters from the electron
(see the figure).
