- 23. Please give detailed answer.What is the momentum of a garbage truck that is 14500 kg and is moving at 10.0 m/s ? momentum: kg⋅m/s At what speed would a 9.35 kg trash can have the same momentum as the truck? speed: m/s5. The Serengeti region of central Africa is home to a myriad of animal species, including the impala, Thomson's gazelle, and the fastest land animal, the cheetah. On one particular day, a 64-kg impala is running at 45 km/h due north, and a 25-kg Thomson's gazelle is running at 77 km/h due east. If a chasing cheetah with a mass of 70 kg has twice the momentum as the impala and gazelle combined, find the direction and magnitude of the cheetah's velocity.
- "The fastest throw of a rugby ball was 48.0 mph (77.25 km/h) and was achieved by Joe Simpson (UK), a professional rugby player for London Wasps, in an event organized [...] in 2011" (source: Guinness World Records) At what speed must a 150-kg rugby player be moving to have the same momentum as the 450 g rugby ball recorded in the Guinness World Records?Answer: _____ Units:______Cuttlefish use jet propulsion to move rapidly. To do this, a cuttlefish fills its muscular mantle cavity with water and then quickly expels the water through a tube-like opening. The mass of a cuttlefish is about the same as the mass of water of the same volume. A 14-cm-long and 6.0-cm-wide cuttlefish, initially at rest, is moving at a speed of 4.0 m/sm/s after expelling the water from its body. Assume that the cuttlefish has a cylindrical form, the mantle cavity has a form of a cylinder with a length of 9.0 cm, and the thickness of the muscle surrounding the sides of the cavity is 1.0 cm. Estimate the speed of the expelled water relative to the sea bed. Express your answer with the appropriate units.A 55.0 kg boy runs at a speed of 16.0m/s and jumps onto a cart that is initially at rest.
