A children’s roller coaster is released from the top of a track. If it’s maximum speed at ground level is 8 m/s, find the height it was released from

80 miles per 80 miles per hour so Likud those up So the kid throws up

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

33: i think it’s b
