To win publicity for her new CD release, Sharika, the punk queen, jumps out of an airplane without a parachute. She expects a stack of loose hay to break her fall. If she reaches a speed of 120 km/h prior to impact, and if a 35 g deceleration is the greatest deceleration she can withstand, how high must the stack of hay be in order for her to survive? Assume uniform acceleration while she is in contact with the hay.
