Find the mass and weight of a body if a resultant force of 850 N causes its speed to increase from 6 m/s to 15 m/s in a time of 5s.

Hi! Let's see.

Explanation:

Data:

==================================================================

In order to calculate the mass, we must first find the acceleration.

to find the acceleration, we apply the acceleration formula in UARM:

Replace per data:

We subtract in the numerator:

It divides:

==================================================================

Mass

Knowing it's acceleration, we can proceed to calculate the mass, applying it's formula:

Replace:

Newton equivalents to kilograms:

Simplify the m/s²:

It divides:

The mass of the body is 472.22 kilograms.

==================================================================

Weight

To calculate the weight, we use it's formula:

Replace:

It multiplies:

The weight of the body is 4627.75 Newtons.

Final

Mass = 472.22 kg

Weight = 4627.75 N.
