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 :

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
