You throw a stone with a force of 55.1 N. It accelerates at 41.6 m/s2.
Mice21 [21]

Answer:

Mass = 1.3 Kilograms.

Step-by-step explanation:

Given the following data;

Force = 55.1 N

Acceleration = 41.6 m/s²

To find the mass of the stone in kg;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Substituting into the formula, we have;

55.1 = mass * 41.6

Mass = \frac {55.1}{41.6}

Mass = 1.3 Kilograms

. If y varies directly with x, and y = -35 and x=7, what is x when y = -85?
sertanlavr [38]

Answer:

x = 17

Step-by-step explanation:

Direct variation is given by

y = kx  where k is the constant of variation

-35 = k*7

-35/7 = k

-5 = k

y = -5x

We know y = -85

-85 = -5x

Divide each side by -5

-85/-5 = x

17 =x
