A8.0 kg object is sliding down s frictionless inclined ramp at an acceleration of 2.6/s/s. what is the angle of the inclined plane

Explanation:

There is only one force acting along the direction parallel to the plane: the component of the weight parallel to the incline, which is given by

where

m = 8.0 kg is the mass of the object

is the acceleration of gravity

is the angle of the incline

Therefore, the equation of motion along this direction is

where

is the acceleration of the object

Re-arranging the equation, we can solve to find the angle of the incline:

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
