The nuqaq is a throwing board (or and atlati) that have been used by first nations hunters for Even when vehicles approach an Intersection at the same speeds, rear end collisions happen more than 26000 years. It Is still used because it is better than a gun for hunting seal In fresh water. A seal shot In salt water will float, but those shot is fresh water will sink and be lost. The when lighter vehicles cut into the lane of larger vehicles just before a stop light. spear point of a nuqaq is attached to a long cord. When a seal, the shaft of the spear will detach and trail behind the seal on the cord, indicating where the seal is so it can be harvested. Spears thrown from a nuqaq give amazing mechanical advantage, so the spear can reach speeds of 150 km/h. Truck -car ... momentum | Explain how this rear end collision happens from elther the point of view of kinetic energy or MOBIBE U S X2 x2 C x Inuit Kayaker by David Stanley Throwing spears with the nuqaq requires practice because as the spear is propelled forwards, he boat is propelled backwards, making distance difficult to judge. Use the following to solve for the following two questions. The boat and person have a mass of 85 kg. The 1.5 kg spear moves with a velocity of 33 m/s right. What is the velocity of the boat after the spear is thrown? Before collision Write the numerical expression that would be used to solve this problem. 4.5 m/s 3.0 m/s 4 - OBI BE O m = 1.8 kg 38 US X2 x2 G C M = 1.2 After collision C X Q 1 m/s Give the value for the unknown velocity? Write the numerical expression that would be used to solve for the unknown velocity. (make sure your signs are correct)
