Find the `SI` unit of speed and acceleration.

Explanation

`"speed"=("distance")/("time")=("meter(m)")/("second(s)")=m//s("called as meter per second")`
`"acceleration"=("velocity")/("time")=("displacement/time")/(time")`
`=("displacment")/("(time)"^(2))=("meter")/("second"^(2))=m//s^(2)`
(called as meter per second square)
