Q1. 0.7 kg block of ice is sliding by you on a very slippery floor at 3 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.003 seconds. The block eventually slides at an angle of 28 degrees from its original direction (labelled in the diagram). The overhead view is somehow alike to scale. The arrow represents the average force your toe applies briefly to the block of ice.
Q2. An elastic cord is 69 cm long when a weight of 57 N hangs from it but is 70 cm long when the weight of 75 N hangs from it. What is the "spring" constant k of this elastic cord?
