On planet Zorg, a 30 kg barbell can be lifted by only exerting a force of 180N. What is the acceleration of gravity on Planet Zo
WITCHER [35]
To calculate g, we use the formula F= mg. F is given as 180N, and m is given as 30 kg, therefore:
180N = (30kg)(g)
g = 6 m.s-1.
The motion of this object would be decreased on Earth as more force would be required to lift it. If we assume g is 9.8 m.s-1 on Earth, we can calculate the force required.
F = mg
   = (30kg)(9.8 m.s-1)
   = 294 N

4x + 6y = 18 & 4x – 2y = 10
kherson [118]

Answer:

x=4.875

y=-0.25

Step-by-step explanation:

4x – 2y = 10

2x-y=10

y=2x-10

4x + 6y = 18

2x+3(2x-10)=9

8x=39

x=4.875

y=2(4.875)-10

y=-0.25

At each mile marker for the first five miles of a marathon, Ellie was 18 seconds, 9 seconds, 14 seconds, 6 seconds, and 3 second
mixas84 [53]
The mean is the average.

Let A = mean

A = (18 + 14 + 9 + 6 + 3)/5

A = 50/5

A = 10

Ellie's mean time is 10 seconds.
