What is the mass of a baseball if the kinetic energy is 122 J
when the baseball is thrown at 103 mph? (in grams)
A batter hits a pop fly, and the baseball reaches an altitude of
230 ft. If we assume that the ball was 3 ft. above home plate when
hit by the batter, what is the ball's increase in potential energy?
(in joules)
An electron has a kinetic energy of 2.17E-17 J. It moves on a
circular path that is perpendicular to a uniform magnetic field of
magnitude 5.13E-5 T. Determine the radius of the path.

A certain reaction has an activation energy of 39.79 kJ/mol. At
what Kelvin temperature will the reaction proceed 6.50 times faster

A certain pen has been designed so that true average writing
lifetime under controlled conditions (involving the use of a
writing machine) is at least 10 hours. A random sample of 20 pens
is selected, the writing lifetime of each is determined, and a
normal probability plot of the resulting data supports the use of a
one-sample t test. (a) What hypotheses should be tested if the
investigators believe a priori that the design specification has
been satisfied?
(b) What...
