What is the acceleration of a car that goes from 0 to 100 m/sec in 2 minutes? (answer in m/sec2)
a = v / t and,
t = 2 min (60sec/min) = 120 sec
so… a = (100m/s - 0m/s)/120 sec
a = m/sec2

A 75-kg parachutist is falling through the air – while experiencing an air drag of 200 N. If they fall from rest for 10 seconds in this manner, how fast are they moving?
v = a t so we must find a…
Fnet = Weight – Drag = ma
So… (75 kg)(9.8 m/s2) – 200 N = (75 kg)a
535 N/75 kg = 7.13 m/s2 = a
