Problems:
35. If you didn’t understand how to do any of the Physics Problems Set (30 practice
problems), make sure you come ask me for help before the start of your class
period. That being said, the following are examples of the type of problems you will
see on your test.
a. Mrs. Willever’s average speed while driving to Colorado last summer was 57
miles per hour. If Denver is 1,500 miles away, how long did it take her to get
there?
b. What stopping time will be required in order to safely stop a 7250 kg CEV
moving at 7.65 m/s with an average force of 426000 N?
c. The Lamborghini Murcielago can accelerate from 0 to 27.8 m/s in a time of
3.40 seconds. Determine the acceleration of this car.
d. The Top Thrill Dragster stratacoaster at Cedar Point Amusement Park in
Ohio uses a hydraulic launching system to accelerate riders from 0 to 54 m/s
(120 mi/hr) in 3.8 seconds before climbing a completely vertical 420-foot
hill. Determine the net force required to accelerate an 86-kg man.
e. Erin and Jarron are members of the stage crew for the Variety Show.
Between acts, they must quickly move a Baby Grand Piano onto stage. After
the curtain closes, they exert a sudden forward force of 524 N to budge the
piano from rest and get it up to speed. The 158-kg piano experiences 418 N
of friction. What is the piano's acceleration during this phase of its motion? If
Erin and Jarron maintain this forward force for 1.44 seconds, then what
speed will the piano have?
f. Moments after making the dreaded decision to jump out the door of the
airplane, Jake's 82.5-kg body experiences 118 N of air resistance. Determine
Jake's acceleration at this instant in time. HINT: begin by determining the net
force.
