## anonymous one year ago The weight (W) of an object is the product of its mass (m) in kilograms and g, the acceleration due to gravity in meters/second2. If the acceleration due to gravity is 9.8 meters/second2, find the corresponding weights for these masses. mass in kilograms = {22.1, 33.5, 41.3, 59.2, 78} The weights (in newtons) for the given masses are

1. Astrophysics

$W = m \times g$ so what's the problem herre?

2. Astrophysics

They have given you the mass, and the gravity which is 9.8 m/s^2

3. Astrophysics

Paying attention to the units, you can see Newton's is the product of kg multiplied by m/s^2. $W = m \times g = kg \times \frac{ m }{ s^2 } = N$

You want weight in newtons so just multiply each of your masses by gravity

7. anonymous

ok so what do I do

8. Astrophysics

$W_1 = 22.1 \times 9.8 = ...$ etc for all your weights

9. Astrophysics

where the subscript 1 represents your first weight using first mass

oh ok
