In Section 1.4, we considered the collision of a karate expert’s hand with a concrete block. Based on the graphs in Figure 1.31, the initial downward speed of the fist with mass 0.75 kg is about -13 m/s and the collision time is approximately 25 ms. Find the impulse and the average force exerted on the block by the fist during the collision.

Use vectors to solve the following problems. Both cars weigh 1500 kg. Use the scale 1 cm = 1,000 kg x m/s. Assume all collisions to be elastic and sticking. Draw a picture represents the problem too. The first car is travelling at 20 m/s east. The second car is travelling at 30m/s north. Using vectors draw to scale the component vectors and the resultant from their collision. Then solve using your trigonometric functions. Also: use Pythagorean Theorem
