(a) 72 m/s (b) 20 m/s (c) 36 m/s (d) 12 m/s

Answer 1

Answer:

(b) 20 m/s

Explanation:

So, 72 kilometers per hour = 72 × 0.27777777777778 = 20 meters per second. To calculate a kilometer per hour value to the corresponding value in m/s, just multiply the quantity in km/h by 0.27777777777778 (the conversion factor).

1 km=1000m

1hr=3600sec

72km/hr

=

$72 km | hr \times \frac{1000}{3600} = 20m |sec$
