A satellite in outer space is moving at a constant velocity of 20.7 m/s in the y direction when one of its onboard thruster turns on, causing an acceleration of 0.310 m/s2 in the x direction. The acceleration lasts for 49.0 s, at which point the thruster turns off.
(a) What is the magnitude of the satellite's velocity when the thruster turns off?
(b) What is the direction of the satellite's velocity when the thruster turns off? Give your answer as an angle measured counter clockwise from the +x-axis.

a)24.73 m/s

b)58.56°

Explanation:

given:

=20.7 m/s

t=49 s

a=0.3

solution:

a)

= = 20.7 m/s

=0

=  + at

   = 0 + 49 x 0.3

   = 14.7 m/s

magnitude:

   =        

   =24.73 m/s

b)

angle =tan-1

         = 58.56°

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
