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 2 ˆˆ ˆ ˆ ˆ ( ) (3.00 i 4.00 j + 2.00k) (3.00 m/s)i (8.00 m/s) j d vt t t t dt =− = (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
