A crate is resting on the floor. An upward force of 80 N is required to lift the crate at a constant speed.
Assume that the gravitational field strength g=10 N/kgg = 10\text{ N/kg}g=10 N/kg.
Which of the following correctly describes the mass and weight of the crate?
Mass =8 kg= 8\text{ kg}=8 kg, Weight =80 N= 80\text{ N}=80 N
Mass =80 N= 80\text{ N}=80 N, Weight =8 kg= 8\text{ kg}=8 kg
Mass =80 N= 80\text{ N}=80 N, Weight =800 kg= 800\text{ kg}=800 kg
Mass =800 kg= 800\text{ kg}=800 kg, Weight =80 N= 80\text{ N}=80 N
