Q. A 0.7 kg block of ice is sliding by you on a very slippery floor at 3.5m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.003 seconds. The block eventually slides at an angle of 22 degrees from its original direction (labeled θ in diagram). The overhead is in the order of to scale. The arrow represents the average force your toe applies briefly to the block of ice.

What is the unit vector in the direction of block's momentum after the kick?
