9.) The 17 kg shopping cart carries a 73 kg child. The shopping
cart wheel base b = 480 mm and its vertical CG is symmetrically
located 580 mm above the floor surface. The child remains centered
symmetrically between the cart wheels with her vertical CG located
750 mm above the floor surface. Determine (a) location above the
floor of the vertical CG of the cart + child in mm and (b) the
tipping angle in degrees.
