Answer:
55 8/39 N ≈ 55 N
Step-by-step explanation:
The net force on the 1.4 kg block is proportional to its mass. That is, the ratio of net force on that block to the net force on the total mass is the same as the ratio of the block's mass to the total mass.
net force on 1.4 kg = (1.4 kg)/(1.4 +6.4 kg) × (64 N -15 N) = (7/39)(49 N)
net force on 1.4 kg = 8 31/39 N
Then the force applied by the 6.4 kg mass is ...
64 N - 8 31/39 N = 55 8/39 N ≈ 55 N . . . . applied by 6.4 kg mass
Answer:
u= -8/17 [-8, ∞)
Step-by-step explanation:
solve it like regular equation
17u≥-8
divide 17 on both side
then you get u≥-8/17
so, (u) is any value greater than or equal to -8/17
less than equal means solid dot on number line i think its called also mean ([) meaning it includes this value too. It is a multiplication so it can be any number above -8 or -8 itself. Thus, the interval notation will be [-8, ∞). Infinite is not a fix number so we use this (). hope this helps good luck
