B3 NEWTON'S LAws B3-RT01: PACKAGES MOVING ON A CONVEYOR BELTNET FORCE Various packages with different masses are moying on a constant-speed conveyer belt. At the instant shown below, all packages have the same constant velocity of 2 m/s directed to the right. The packages do not slip on the belt. All masses are given in the diagram in terms of M, the mass of the smallest package. v = 2m/s i A B Cc D E Rank the magnitude of the net force on each package. 2 P Y 1 Greatest _Least thesame _ zero determine; i i R e Explain your reasoning. Constant velocity means the objects are covering the same distance in same interval of time. When velocity is constant acceleration is zero. If acceleration is zero no force is acting on pacakge.Thus force on all pacakages are zero. B3-RT02: WATER SKIERSNET FORCE Water skiers are pulled at a constant speed by a towrope attached to a speedboat. Because the weight of the skiers and the type of skis they are using varies, they experience different resistive forces from the water. Values for this resistive force (RF) and for the speed of the skiers are given. Rank the magnitude of the net force on each water skier.
