1.	Cars pass a point travelling at 45.0(5), 47.0(7) 50.0(9), 53.0(4) and 57.0(1)km h^(-1). The numbers in brackets give the number of cars with respective velocities. Calculate the RMS velocity and average velocity.
Answer» SOLUTION :RMS VELOCITIES 49.06km`H^(-1)` ,AVERAGE velocities 48.96km`h^(-1)`
