PHYS 1010 Final Exam
/. A squirrel runs along an overhead telephone wire that stretches from the top of one
pole to the next. The creature is initially at position xi=2.91 m, as measured from the
center of the wire segment. It then undergoes a displacement of Δx=-5.61 m. What is
the squirrel/'s final position xf? - Answer--2.70 m
/.Identify the vector quantities below:
14.4 m/s South
578.0
39.9 ft
16.3 m at 25.7°
6.24 m - Answer-14.4 m/s South
16.3 m at 25.7°
/.One mile is equal to 1.609 km. What is 30.0 mph in m/s? - Answer-13.4 m/s
/.After an average acceleration of 3.39 m/s2 during 2.29 s, a car reaches a final velocity
of 16.1 m/s. Find the car's initial velocity. - Answer-8.3 m/s
/.A fox locates its prey under the snow by slight sounds rodents make. The fox then
leaps straight into the air, and then burrows it's nose into the snow to catch its meal. If a
fox jumps up to a height of 91 cm, calculate the speed at which the fox leaves the snow,
and how long the fox is in the air. Ignore air resistance. - Answer-4.2 m/s and 0.86 s
/.Five students are asked to draw a motion diagram for a baseball falling downward
after being released from rest. which student's diagram correctly represents the motion
of the falling ball. - Answer-Sue
/.Vector A has a magnitude of 13.5 and is 345o counter-clockwise up from the +x-axis.
What are the x- and y-components of the vector? - Answer-13.0 and -3.49
/.After being pushes, a hockey puck is simply sliding of the ice with no friction. If the
velocity is measured over time, which of the following graphs best represents what you
would expect to measure? - Answer-B
/.- - Answer--
/.A 2.03 kg book is placed on a flat desk. Suppose the coefficient of static friction
between the book and the desk is 0.542 and the coefficient of kinetic friction is 0.294.
How much force is needed to begin to move the book and how much force is needed to
keep the book moving at a constant velocity? - Answer-10.8 N and 5.85 N
