Important part of science--both
the interest in new or different ideas---open-mindedness
if not checked, it can prevent progress--skepticism
if not checked, it can lead to ideas being accepted without significant evidence to support them---open-mindedness

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?
