During a race a cyclist changes speed from 48 kph (km/hr) to 27 kph. if this was done in 15 seconds what was her acceleration in km/hr2?
pick the correct answer from the ranges below.

-5040 km/h²

Explanation:

Average acceleration a is given by:

a = Δv/Δt

a = (27km/h - 48km/h) * 60m/h * 60s/m / 15s

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
