Question

(a) Block A with a mass of 1 kg and block B with a mass of 2 kg lle on a smooth table. You wish to apply a hortzontal force to each ball to give safely ignore friction). Which of the following best describes the relative m agnitude of the forces you must apply? them the same hortizontal acceieration (and ○The magnitude of the force on block A must be twice as much as the force on ) The magnitude of the force on block B must be twice as much as the force on block A O Both forces must have the same magnitude. O More information is needed to determine the relative magnitudes of the forces. (b) Block A has a mass of 1 kg and block B has a mass of 2 kg. Which of following best describes the relative magnitudes of the gravitational force (due to the Earth) on each block? O The gravitational force on block A is twice as much as the gravitational force on block B O The gravitational force on block B is twice as much as the gravitational force on block A O Both gravitational forces have the same magnitude. More information is needed to determine the relative magnitudes of the forces (c) You hold block A with a mass of 1 kg in one hand and block B with a mass of 2 kg in the other. You release them both from the same height above the ground at the same time. (Air resistance can safely be ignored as they fall.) Which of the following describes and explains the motion of the two objects after you release them? before the block B. The same force of gravity acts on both objects, but because block A has a lower mass, it will have a larger acceleration Block B hits the ground before the block A. The larger force on block B causes it to have a greater acceleration than block A, The two blocks hit the ground at the same time, because they both ackelerate at the same rate while falling. The greater gravitational force on block B is compersated giving it the same acceleration. start failing faling. The forces on the blocks are irrelevant once they e, because they both move at the same constant speed while D The two blocks hit the ground at the same tim Submit AssignmentSave Assignmert Progress

Answer 1

a) the magnitude of force on B block is twice than the A block.

b) the magnitude of gravitational force on block B is twice the gravitational force on block A

C) since there is no air friction force both blocks reaches at the same time.
