The following questions may result in amusing answers.
I am continuing to work on putting into words the many valuable bits of wisdom I have gained in English class, but as my next installment of this great work that is not yet quite ready and it has been too long already since I posted something, I am going to share some of my homemade physics problems. On occasions when I finished a Physics test early I enjoyed writing this sort of question back to my teacher on a blank spot on the page, and he wrote the solution back along with my mark. All four of the problems below deal with mechanics, and all four can be and have been solved.
1. Rhyhorn (254 lbs = 115 kg), using the technique Take Down, hits a stationary Oddish (12 lbs = 5.4 kg) at a velocity of 7.0 ms-1. After the collision, Rhyhorn continues to move forward at a speed of 6.0 ms-1 and all its other momentum is transferred to Oddish, who flies backwards through the air. What is the maximum velocity at which Oddish hits the ground?
2. The amount of damage dealt by the technique Take Down varies directly with the momentum with which the target hits the ground. When a move is a Critical Hit, twice as much damage is dealt. Rhyhorn (in #1) did not deliver a Critical Hit against Oddish. How much kinetic energy would Rhyhorn have had after the collision if it had?
3. The magical nature of the Thundershock attack is such that the target Pokémon is held in place for the duration of the attack and then, when the attack is complete, is propelled backwards through the air by the energy it has absorbed. Pikachu blasts a Blastoise (189 lbs = 86 kg) with Thundershock for a duration of 0.50 s. Blastoise flies backwards through the air a distance of 6.0 m and is airborne for 1.1 s. What is Pikachu’s lowest possible power (in Watts)?
4. Under the influence of Quick Attack, Pikachu (13 lbs = 5.9 kg) runs towards Blastoise with an acceleration of 2.0 ms-2. Blastoise directs its Hydro Pump attack against Pikachu when Pikachu’s velocity has reached 10.0 ms-1. Pikachu continues to attempt to run forward with same force. Hydro Pump has a duration of 4.0 s and exerts a constant force opposing Pikachu. When the attack is complete, Pikachu’s velocity is 2.0 ms-1. Blastoise does not move. What is the minimum frictional force between Blastoise and the ground?
