Answer:

(a) 918.37 kg

(b) 2020.41 lbs

Explanation:

number of students = 20

Force of each student = 450 N

Total upward force = 450 x 20 = 9000 N

(a)

Let m be the mass of car

F = m x g

9000 = m x 9.8

m = 918.37 kg

(b)

As we know that, 1 kg = 2.20 lbs

So, 918.37 kg = 2.20 x 918.37 = 2020.41 lbs

If the mass of a person is 600kg on Earth what is the persons mass on the moon
nika2105 [10]

Answer:

The mass of the person would remain 600kg.

when asked about weight, it would be 1000N. but in mass , same 600kg.
