The object of mass m 1 = 6.60 kg is released from rest at a height h = 3.40 m above the table. • a)Using the isolated system model, determine the speed of the object of mass m 2 = 3.00 kg just as the 6.60kg object hits the table. • b)Find the maximum height above the table to which the 3.00kg ... WebScience Physics A 40-kg boy is sliding on a horizontal and frictionless surface with an initial momentum of 90 J due east. When t=0, a force, as a function of time, F=8.20t is applied to the boy due west. At what value of t will result in the momentum of the boy 60 J due west? What is the acceleration of the boy at that time computed in (a)? a. b. ifort -c
