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).

Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J
Answer:
C: The Assyrians became skilled warriors and invented of the battering ram.
Explanation:
The Assyrians were outstanding combatants. They had iron weapons and were amazing engineers. Assyrians had a fully equipped and professional standing army and were ruthless in battle which will later lead to their downfall. They also invented the battering ram and many military tactics that helped them expand their empire at a quicker pace.
