After reading the brief summary of the newtonian worldview and dewitt's concluding remarks, identify an aristotelian belief that than the newtonian one. (if you find this difficult, pretend you are someone less wise.) explain why this is so.

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.

Calculate a pendulums frequency of oscillation (in hz) if the pendulum completes one cycle in 0.5s.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2 . how much is the spring compressed x from its natural length?
