1. show how the relation F/W=a/g is obtained.
2. A 10-kg box, initially at rest on the flor, is pulled by a constant force of 20 newtons for 5 seconds. With what velocity is the box moving at the end of 5 seconds?
3. A car at rest which acted upon by a constant force acquires a velocity of 22 m/s after 4 seconds. Determine the magnitude of the constant force if the car weighs 10800 newtons.
