Question

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?

Answer 1

The block’s average speed : 0.36 m/s

Further explanation

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

Average speed = total distance/total amount of time ,

Can be formulated :

`\tt avg.s(speed)=(\Delta D)/(\Delta t)`

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 :

`\tt avg.s=(0.9)/(2.5)=0.36~m/s`
