Question

utilize as equações do MRU e encontre as incógnitas desconhecidas: 1) V = 450 m/s, D = 900 m, T = ?2) D = 700 km/h, T = 70 km/h, V = ?3) V = 15 m/s, T = 20 s, D = ?

Answer 1

1)
Vm = D / T
450 = 900 / T
T = 900/450
T = 2 s

2)
Vm = D / T
Vm = 700 / 70
V = 10 km/h

3)
15 = D / 20
D = 15 . 20
D = 300 m
