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...

You throw a rock with an initial speed of 30 m/s and an angle of 50 degrees with respect to the vertical. The field you are on is however not horizontal but is inclined by an angle of 10 degrees with respect to and above the horizontal. Choose a coordinate system whose origin is located where the rock is thrown, and a rotated system such that the positive y axis is positive at an angle of 100 degrees measured counterclockwise...

A sinusoidal transverse wave is traveling along a string in the
negative direction of an x axis. The figure below shows a
plot of the displacement as a function of position at time
t = 0. The x axis is marked in increments of 10
cm and the y axis is marked in increments of 2 cm. The
string tension is 3.1 N, and its linear density is 34 g/m.

Wave on a String A string with linear mass density 2.0 g/m is stretched along the positive x-axis under a tension of 20 N. The other end of the string, at x = 0m is tied to a hook that oscillates up and down at a frequency of 100Hz with a maximum displacement from equilibrium of 1.0 mm. At t= 0s, the hook is at it's lowest point. (a) What are the wave speed and the wavelength on the string?...
