10)A car is moving from rest and attained a velocity of 80 m/s. Calculate the acceleration of the car after 5 s?

initial velocity (u)=0

final velocity (v)=80m/s

time(t)=5s

acceleration (a)=?

Explanation:

we have

v=u+at

80=0+a×5

5a=80

a=80/5=16m/s²

there are no atoms

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
