6. To emphasize the fact that the velocity is a function of time, we adopt the notation v(t)for/.dx dt(a) Eq. 4-10 leads to 2ˆˆˆˆˆ( )(3.00 i 4.00 j + 2.00k)(3.00 m/s)i (8.00 m/s) jdvttttdt=−=−(b) Evaluating this result at t= 2.00 s produces = (3.00i 16.0j) m/s.v−G(c) The speed at t= 2.00 s is 22| |(3.00 m/s)( 16.0 m/s)16.3 m/s.vv==+−=G(d) The angle of
