Question

boa tarde me ajudem pfv​

Answer 1

a)

v = x - x0 / t

v = 3 (m) - 1 (m) / 4  (s)

v = 2 (m) / 4 (s)

v = 0,5 (m/s)

x = x0 + v t

x = 1 + 0,5 t

b)

v = x - x0 / t

v = 9 (m) - 3 (m) / 2 (s) - 0 (s)

v = 6 (m) / 2 (s)

v = 3 (m/s)

x = x0 + v t

x = 3 + 3 t

c)

v = x - x0 / t

v = 9 (m) - 0 (m) / 3 (s) - 0 (s)

v = 9 (m) / 3 (s)

v = 3 (m/s)

x = x0 + v t

x = 0 + 3 t

x = 3t
