Answer:

1000 g of rice

Step-by-step explanation:

since 2 people eat 400 grams

each person eats 400/2 grams = 200 grams

so 5 people is 5(200 g)=

1000 g

Answer:

1000 g of rice

Step-by-step explanation:

Recipe states that every 400g of rice feeds 2 people. Thus, it can be concluded through division (400 ÷ 2) that every person is fed with 200g of rice.

If you want to feed 5 people, then multiply 200 (amount of grams that feeds 1 person) by 5 (the number of people)

200 × 5 = 1000

1000 grams of rice is needed for 5 people.

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

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

$Mass = \frac {55.1}{41.6}$
