A spring of spring constant k = 500 N/m hangs down from the ceiling. You attach a mass of 2kg to the bottom of the spring and let go. How far does the spring extend before first momentarily stopping. The answer is in centimeters.

A particle moves in the x-y plane according to r(t) = (4 + 3t3) i + (2 + 2t4) j.  Here distances are measured in meters and times in seconds.  At t = 2 seconds, what angle does the velocity of the particple make with the x-axis?

A hiker travels 1 mile east, then 1 mile northwest, and finally 2 miles south.  How far away are they from their starting point?

You balance a 2 kg block on the palm of your hand. You then lower it, very slowly and gently, a distance of 1.0 meters.  What work do you do on the block? (in Joules)

A block of mass M is on a table with no friction acting. It has a horizontal rope attached that goes over a pulley and a block of mass m hangs from it. It is found that the subsequent acceleration of the blocks is “a”, with of course the block M accelerating horizontally and m accelerating vertically. If you instead pull the rope down with your hand (that is replacing the mass m with a force F down), what value of F would you need to get M to accelerate with the same value “a”?  

A day on Jupiter is 9 hours and 56 minutes long.  How many minutes are in 2 weeks on Jupiter (14 Jupiter days)?

A man has a mass of 80 kg. He stands on a bathroom scale in an elevator, and the elevator moves up. As it gets close to the top floor, it slows uniformly from 4 m/s to a stop in a time of 2 s. During this time, what does the scale read (in kg)?

A bowling ball hangs from a rope which hangs from a hook which is itself attached to the ceiling. If you call the force of gravity on the ball the “action” force, what is the “reaction” force paired with it by Newton’s Third Law?

Which of the following descriptions illustrates phenotype variation caused by environment?

Which statement about the beak size of finches on the island of Daphne Major during prolonged drought is true?
