Answer:
18.60 m/s
Explanation:
Original momentum = mv = 4000 with m = 115
after collision m = 115 + 100 = 215 kg
but the total momentum is still the same (conserved)
4000 = 215 v shows v = 18.60 m/s
Kinectic Energy=1/2(mass)(velocity)^2 so 1.2=1/2(.0012)(position/2) so it travels 4000 m. Not sure how it is 293.2 ft
first is gamma Ray's, last is d
Take into account that conduction is the process at which heat is propagated by the termical motion of the molecules, without a real desplacement of the molecules.
Based on the previous definition, the following is an example of heat transfer by condu
