H = 280 ft, the height of the flower pot. g = 32 ft/s²
Neglect air resistance. Note that 1 ft/s = 15/22 mi/h
The initial vertical velocity is zero. Let v = the velocity with which the flower pot hits the ground. Then v² = 2gh = 2*(32 ft/s²)*(280 ft) = 17920 (ft/s)² v = 133.866 ft/s
Also, v = (133.866 ft/s)*(15/22 (mi/h)/(ft/s)) = 91.272 mi/h
the east west bit isn't important, ignore it. if an ant starts at 6 then moves to 19 then we need to subtract 19 from 6, that's 13. then it moves to 7. the difference between 19 and 7 is 12. add that to 13 and you get 25. it's important to remember that there is no such thing as negative distance. if it moved, then it counts.
P=4800kgm/s As p=mΔv where p is momentum, m is mass and v is velocity Given values is m =1200kg Δv= 17m/s-13m/s=4m/s Now p=mΔv p=(1200kg)*(4m/s) p=4800kgm/s
I think it's a solar power might seem strange or futuristic but it's already quite common place you might have a solar powered quartz watch on your wrist or solar powered pocket calculator
