Question

4. Express each of the following in m/s
(a) 65 cm/s
(b) 367 km/h
(c) 1000 cm/min (d) 86 km/min​

Answer 1

Step-by-step explanation:

a).

1cm = 0.01m

so,

65 cms^-1 = 0.65 ms^-1

b).

367 kmh^-1 = (367×5÷18) ms^-1

c).

1000 cm/min = (1000×60÷100) ms^-1

d).

85 km/min = (85×60÷1000) ms^-1
