Answer 1

C. Vertical velocity of computer after 0.6 s is given by

$v_{y} = v_{y0} + gt$

Plugging in the values

$v_{y} = 24 sin 30 + 9.8*0.6$

$v_{y} = 17.88 m/s$

Magnitude of velocity is given by

$v = \sqrt{v_{y}^{2}+v_{x}^{2}}$

Plugging in the values

$v = \sqrt{24 cos 30^{2}+17.88^{2}}$

$v = 27.42 m/s$

Thus the magnitude of velocity after 0.6 s is 27.42 m/s
