Physics Puzzle #1 Mystery Cache

A tip of the hat to denjoa for providing various puzzle caches and providing inspiration for these puzzles.

And congratulations to denjoa for getting FTF honours on this cache!

One of the topics examined in Physics, is Kinematics or the study of motion.  This will be a series of nine puzzles that will look at problems related to Kinematics.

This series of caches is reaching the end of its run. 

I will be archiving them in August 2022

It is recommended, but not necessary, that you complete the puzzles in order as each puzzle will have an increasing level of difficulty. The puzzles in the series are

Physics Puzzle #1 (GC6XBGC)

Physics Puzzle #2 (GC6XDN0)

Physics Puzzle #3 (GC6XDXM)

Physics Puzzle #4 (GC6XK5Q)

Physics Puzzle #5 (GC6XMW4)

Physics Puzzle #6 (GC6XP3J)

Physics Puzzle #7 (GC6XXY3)

Physics Puzzle #8 (GC6XY1H)

Physics Puzzle #9 (GC6XY50)

The Lesson

A little bit of terminology is needed to start off.

time - the duration between two events

       - in Physics the basic unit for time is the second (s)

distance - the separation between two points

       - the basic unit for distance is the metre (m)

speed - the rate of change of distance or the rate at which an object is moving

       - speed is measured in metres per second (m/s)

       - For reference, a speed of 80 km/h is approximately 22 m/s (divide by 3.6)

acceleration - the rate of change of speed or the rate at which an object's speed is changing

       - the units used for acceleration are a combination of speed and time as metres per second per second usually shown as m/s²

       - acceleration can be positive for an object speeding up or negative for slowing down

The Puzzle

Read the following statements:

     In a NASCAR race, one car is travelling at 85 m/s before undergoing a change at 5.4 m/s² for 2.7 s.

     A record breaking skateboarder travelled at approximately 39 m/s

     A rock falls at 9.8 m/s².

     The world record cliff dive had the diver falling at 51 km/h for 58.8m.

     Another record was set by an electric car travelling at 18 m/s².

From the above problems, which of the numbers shown represent an acceleration? In the order they appear above, enter the digits in the spaces below.

If necessary, convert to the proper units and round off any numbers so that you have only two digits.

       A = __ B = __ C = __ D = __ E = __ F = __
