![]() ![]() Weight of block B (w B ) = (0.3 kg)(10 m/s 2 ) = 3 kg m/s 2 = 3 Newton Weight of block A (w A ) = (0.1 kg)(10 m/s 2 ) = 1 kg m/s 2 = 1 Newton Mass of block B (m B ) = 300 gram = 0.3 kg Mass of block A (m A ) = 100 gram = 0.1 kg Determine the normal force exerted by block B on block A. Block A with a mass of 100-gram place above block B with a mass of 300 gram, and then block b pushed with a force of 5 N vertically upward. The direction of force F rightward, the direction of friction force leftward (the direction of friction force is opposite with the direction of object’s motion).Ĭhoose rightward as positive and leftward as negative.ħ. ∑ F = net force, m = mass, a = acceleration The equation of Newton’s second law of motion Determine the magnitude of friction force experienced by the block. The direction of the acceleration = the direction of the net force = direction of F 1Ī 40-kg block accelerated by a force of 200 N. The magnitude and direction of the acceleration is… F 1 = 10 Newton, F 2 = 1 Newton, m 1 = 1 kg, m 2 = 2 kg.

Object’s mass = 2 kg, F 1 = 10 Newton, F 2 = 1 Newton. The magnitude and direction of the acceleration is…ĭirection of the acceleration = direction of the net force = direction of F 1Ĥ. ![]() Object’s mass = 2 kg, F 1 = 5 Newton, F 2 = 3 Newton. The direction of the acceleration = the direction of the net force (∑F)ģ. Wanted : The magnitude and direction of the acceleration (a) Determine the magnitude and direction of the object’s acceleration…. Mass of an object = 1 kg, net force ∑F = 2 Newton. We use Newton’s second law to get the net force. Estimate the net force needed to accelerate the object. A 1 kg object accelerated at a constant 5 m/s 2.
