Answer
(a) $p_x = -30~kg~m/s$
$p_y = -55~kg~m/s$
(b) $p_x = 0$
$p_y = 52.0~kg~m/s$
(c) $p_x = 0$
$p_y = -3.04~kg~m/s$
Work Step by Step
(a) $p_x = (10.0~kg)(-3.0~m/s) = -30~kg~m/s$
$p_y = (5.0~kg)(-11.0~m/s) = -55~kg~m/s$
(b) $p_x = (6.0~kg)(10.0~m/s)~cos(60^{\circ})+(10.0~kg)(-3.0~m/s)$
$p_x = 0$
$p_y = (6.0~kg)(10.0~m/s)~sin(60^{\circ})$
$p_y = 52.0~kg~m/s$
(c) $p_x = (6.0~kg)(10.0~m/s)~cos(60^{\circ})+(10.0~kg)(-3.0~m/s)$
$p_x = 0$
$p_y = (5.0~kg)(-11.0~m/s)+(6.0~kg)(10.0~m/s)~sin(60^{\circ})$
$p_y = -3.04~kg~m/s$
