A block is pulled 0.90 m to the right in 2.5 s. What is the block’s average speed to the nearest hundredth of a m/s?

The block’s average speed : 0.36 m/s

Distance is the length traveled by an object within a certain of time .  

Average speed = total distance/total amount of time ,

Can be formulated :

ΔD= total distance

Δt= total time

A block is pulled 0.90 m to the right in 2.5 s :

ΔD= total distance = 0.9 m

Δt= total time = 2.5 s

The block’s average speed :

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
