Atrain travels 53 kilometers in 2 hours, and then 54 kilometers in 4 hours. what is its average speed? your answer units

Average speed = (total distance) / (time to cover the distance)

total distance = (53 km + 54 km) = 107 km

time = (2 hr + 4 hr) = 6 hours

Average speed = (107 km) / (6 hrs)

Average speed = (107/6) (km/hrs)

Average speed = 17.833... km/hr

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
