(6) a mass weighing 16 pounds stretches a spring 2 feet. att=0 the mass is released at a equilibrium position with a downward velocity 10 ft/sec. it is known that the surrounding medium offers a resistance numerically equal to the instantaneous velocity. if the mass is driven by f(t) 10 cos (2t), find the equation of motion of the mass and the initial conditions. (do not solve the equation) point 2 feet above the an external force equal to (8) a mass weighing 8 pounds stretches a spring 2 feet. at t= 0 the mass is released from rest from a point 10 feet above the equilibrium position, determine the motion of the mass. the-c

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
