A roadrunner is running along a straight desert road at a constant velocity of 25 m/s. If a certain coyote wants to capture the roadrunner using a net dropped from an overpass that is 10m high, how much time before the roadrunner is under the overpass, should the coyote drop the net? How far away from the overpass is the roadrunner when the coyote drops the net?

Auniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance of 1.60 cm . a proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval of 3.20×10-6 s. 1-find the magnitude of the electric field. use 1.60×10-19c for the magnitude of the charge on an electron and 1.67×10-27kg for the mass of a proton 2-find the speed of the proton when it strikes the negatively charged plate
