Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5
Answer:
The weight for an object with a velocity of 12 meters per second is 600 kilograms
Step-by-step explanation:
Formula of linear momentum : p = mv
where p is the momentum
m = mass
v = velocity
If the velocity is 16 meters per second and the object weighs 450 kilograms
Substitute the values
We are supposed to find the weight for an object with a velocity of 12 meters per second
So, p = 12m
We are given that The linear momentum is a constant when the mass varies inversely of the velocity.
So,
600 = m
So,the weight for an object with a velocity of 12 meters per second is 600 kilograms
