A) Uniform retardation of\[0.02\,\,m\,\,{{s}^{-2}}\]
B) Uniform acceleration of\[0.02\,\,m\,\,{{s}^{-2}}\]
C) Uniform retardation of\[-0.04\,\,m\,\,{{s}^{-2}}\]
D) Uniform acceleration of \[-0.04\,\,m\,\,{{s}^{-2}}\]
Correct Answer: A
Solution :
Compare the given equation, with \[v=u+at\], we get \[u=6\,\,m\,\,{{s}^{-1}};\,\,a=-0.02\,\,m\,\,{{s}^{-2}}\] The - sign indicates retardation.
