A car of mass M = 900 kg traveling at 65 km/hour enters a banked turn covered with ice. The road is
banked at an angle e, and there is no friction between
the road and the car's tires as shown in Figure 1). Use g
= 0.80 m s throughout this problem.

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
