Question

The gas piston of an M4 carbine rifle with in initial position of x0=5[mm].experiences a velocity defined by x’=3+5t for one second. What is the piston’s finale position?

Answer 1

plz solve it in details ...thanks

Answer 2

\[ {dx \over dt} = 3 + 5t \\
\int dx = \int( 3 + 5t) dt = x = 5t^2/2 + 3t + c \\
put, x=0, when \;t = 0 \\
that \; would \; give \; c =5,
\\
now \; put \; t=1
\]
in 5t^2/2 + 3t + 5 and get your answer.

Answer 3

wat is t^2 ???

Answer 4

\[ {5t^2 \over 2} + 3t + 5 \]

Answer 5

yea tanx aloooooooooooooooooooooot it's 10.5 mm
