Question

A 5.00 kg crate is on a 21.0° hill.

Using X-Y axes tilted down the
plane, what is the y-component
of the weight?
(Unit = N)

Answer 1

-45.745

Step-by-step explanation:

it is negative because it is downwards.

Answer 2

17.56 N

Step-by-step explanation:

Given that,

Mass of a crate, m = 5 kg

It is on a 21.0° hill

We need to find the y component of the weight.

y component = mgsinθ

Put all the values,

y-component = 5×9.8×sin(21)

= 49×sin(21)

= 17.56 N

So, the y-component of the weight is 17.56 N.
