Tom is on board a bus moving with a constant velocity in the +x
direction while Fred is standing on the sidewalk. When
the Bus passes Fred, Tom tosses a coin and catches it on its way
back. Both Fred and Tom measure the time interval for the coin
toss. Which of the following observations is correct?
A. Tom will measure a longer time interval for the coin toss and
observe that the coin follows a parabolic path.
B. Fred will...
The displacement of a wave traveling in the negative x-direction
is y(x,t)= ( 5.2 cm )cos( 6.0 x+ 73 t), where x is in m and t is in
s. What is the frequency of this wave? What is the wavelength of
this wave? What is the speed of this wave?
A block of 4 kg moves in the +x direction with a velocity of 15
m/s while a block of 6 kg moves in the +y direction with a velocity
of 10 m/s. They collide and stick together.
Calculate the following: a. What is the momentum in this system?
b. What is the final velocity of the two blocks?
A particle leaves the origin with an initial velocity of 4.10
m/s in the x direction, and moves with constant acceleration ax =
-1.40 m/s2 and ay = 3.80 m/s2. How far does the particle move in
the x direction before turning around? What is the particle's
velocity at this time? Enter the x component first, followed by the
y component.
Find the derivative of the parametric curve x = 6t - t^2, y =
lnt where t > 0
A. Find all values of t where the tangent line is horizontal. After
you find the values of t where the tangent lines are horizontal,
find the corresponding x and y values giving your answers as
ordered pairs.
B. Find all values of t where the tangent line is vertical.
After you find the values of t where the tangent lines...
