      In terms of impulse, how can a karate expert break a stack of bricks with their bare hand? Part 3: Problems. 1. A 4 kg cat runs at a speed of 3 m/s. What is its momentum? 2. A 1000 kg car moving 39 m/s applies a braking force of 20 N how long does it take for it to come to a stop? 3. A 900 kg cannon shoots a 5 kg cannonball at 80 m/s.

      (The Physics of Karate) A karate expert strikes downward with his fist (of mass m1 = 0.70 kg), breaking a 0.14 kg wooden board. He then does the same to a 3.2 kg concrete block. The spring constants k for bending are 4.1 104 Nm-1 for the board and 2.6 106 Nm-1 for the block.

      There is a lot of physics involved in karate in general, and in board-breaking in particular. The same principle works for a board. If my hand is open when I strike the board (slaps the board), even though I hit it hard it doesn't break because the force is spread over a large area.

      Although this is a primarily a non-mathematical physics course, I expect you to have math understanding at the high school level. Explanations will be mainly with words and pictures; only simple mathematical relations will be used to aid in the description of the basics of mechanical, electrical, and optical devices.
