Answer:
The change in momentum equals the area under the graph (the impulse). That area is 4N * 3s - 2N * 2s = 8 N s. Therefore . m delta(v) = 8 kg m/s. 1.2 kg * ( v(6) - v(0) ) = 8 kg m/s
Explanation:
A)An object cannot remain at rest unless the net force acting on it is zero. B) If a block is moving to the left with constant velocity the net force applied to the block is zero. C) A block of mass 2 kg is acted upon by two forces: 3N (directed to the left) and 4N (directed to the right).
The answer is a)growth and development is a gradual
The sky is blue because air molecules in the air scatter blue light from the sun more than they scatter red light.
The correct answer for the question that is being presented above is this one: "3/8" A traffic light near a museum is green for 30 seconds, yellow for 5 seconds, and red for 15 seconds. <span>If 8 vehicles approach the signal, the probability that 3 of them are stopped by the red light is 3/8</span>
