A4000kg truck is parked on a 15.0∘ slope.

how big is the friction force on the truck?

Frictional force, F = 10145.70 N

Explanation:

It is given that,

Mass of the truck, m = 4000 kg

Angle between ground and the truck,

The force that opposes the motion of abject is called frictional force. Here, the truck is at rest. So, the frictional force is given by :

N is the normal force, N = mg

F = 10145.70 N

So, the frictional force on the truck is 10145.70 N. Hence, this is the required solution.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

a, c, d, e are all applying about success strategies.
