Problem
A company installs side air-curtains in buses that deploy just before the vehicle negotiates a sudden right turn at high speed. Which option most correctly states why such lateral airbags can reduce passenger injuries during the turn?
(a) They lessen the passengers’ effective mass, so the inertia that resists turning becomes smaller.
(b) They neutralise the outward centrifugal force produced during the bend, keeping passengers fixed relative to their seats.
(c) They supply the sideways force that changes the passengers’ straight-line motion so that their path curves with the bus.
(d) They cushion the inward push produced by inertia of rest when passengers press toward the centre of the curve.
