(a) What is the mass of the child and basket (in kg) if a scale reading of 82 N is observed?
kg
(b) What is the tension T₁ (in N) in the cord attaching the baby to the scale?
N
(c) What is the tension T₂ (in N) in the cord attaching the scale to the ceiling, if the scale has a mass of 0.620 kg?
N
You drive 5.50 km in a straight line in a direction 15° East of North.
(a) Find the distances (in km) you would have to drive straight East and then straight North to arrive at the same point. (This is equivalent to finding the components of
the displacement along the East and North directions.)
(b) Show that you still arrive at the same point if the East and North legs are reversed in order.
