Question

vm=?
delta s=400 km
delta t=180,000 s

vm=180km\h
delta s=700m
delta=?

vm?
delta s=2700
delta t=7s


vm=340km\h
delta s=68000m
delta t=?


vm=?
delta s=14,4m\s
delta t=2hs



vm=?
delta s=65m
delta t=13s

Answer 1

vm= x
delta s=400 km
delta t=180,000 s
primeiro convertemos os segundos para hora. 180000 s. = 3000 h
VM = s\t = 400\3000 = 0,13 km\h

vm=180km\h
delta s=700m
delta=?
convertermos metros para quilômetros. 700 m = 0,7 km
∆t= ∆s\vm = 0,7\180 = 0,003 horas


vm?
delta s=2700km ou m ???
delta t=7s


vm=340km\h
delta s=68000m
delta t=
converter de metros para km. 68000 = 68 km.
∆t=∆s\vm = 68\340= 0,2 horas

vm=?
delta s=14,4m\s ???
delta t=2hs



vm=?
delta s=65m
delta t=13s
VM=s\t = 65\13 = 5m\s
