QUESTION 1
How long? How much time in seconds does it take for the sled to go down part of a hill?
A sled with a total mass of 671 kilograms is going down a straight part of a hill where the angle of incline is 10.6 degrees.
The length of the straight part of the hill is 76.4 metres.
The speed of the sled at the top of the hill is 4 meters per second.
The combined forces of friction = the total friction including air drag and sliding friction = 43 newtons.
How much time does it take for the sled to travel down the straight part of the hill?
Note that the initial speed is NOT zero and so you will have to solve a quadratic equation to get your answer.
Solutions
Expert Solution
To calculate the time taken by the sled to travel the straight
portion of the hill, we have to know to force acting on the sled in
X and Y direction.Then using equation of kinematics we find the
quadratic equation of t and solving this equation we can find
time.

Does reaction time (measured in seconds) depend on how much
coffee is consumed? Researchers design an experiment in which
subjects are instructed to look at a computer screen and respond as
quickly as possible—by pressing a button—as soon as a particular
stimulus appears on the computer screen. Prior to responding to the
computer stimulus, subjects are either randomly assigned to drink
no coffee, to drink one cup of coffee, or to drink two cups of
coffee. It is observed that...

1. A sled of mass m is pushed for 5 seconds at a constant force.
A sled of mass M (more) is also pushed for 5 seconds. THe force is
the same in each case. WHat is the momentum of each sled? How do
they compare? What is the energy of each sled? How do they
compare?
2. The same question, except that each sled is pushed for 5
meters instead of 5 seconds.

1. How long does it take an ambulance to respond to a request
for emergency medical aid? One of the goals of one study was to
estimate the response time of ambulances using warning lights (Ho
& Lindquist, 2001). They timed a total of 67 runs in a small
rural county in Minnesota. They calculated the mean response time
to be 8.51 minutes, with a standard deviation of 6.64 minutes.
Calculate a 95% confidence interval for the mean for this...
