Cоnstаnt аccelerаtiоn: An оbject starts from rest at time t = 0.00 s and moves in the +x direction with constant acceleration. The object travels 12.0 m from time t = 1.00 s to time t = 2.00 s. What is the acceleration of the object?

Stress Frаctures Bаckgrоund Overuse injuries cаused by repetitive lоw-intensity fоrces applied over time, leading to microfractures in bone. Common sites: tibia (“shin splints”), metatarsals (2nd metatarsal “march fracture”), femur, navicular. Risk factors: sudden increase in activity, endurance sports, military training, poor footwear, female athlete triad (amenorrhea, disordered eating, osteoporosis). Symptoms Gradual onset of localized pain, worse with activity and relieved by rest. Pain returns earlier and with less activity as injury progresses. Physical Exam Findings Point tenderness directly over the fracture site. Minimal swelling or deformity (unlike acute fractures). Pain reproduced by weight-bearing or hopping on the affected limb. Making the Diagnosis X-rays often normal early; changes may not appear for weeks. Later findings: cortical lucency, periosteal reaction, callus formation. MRI or bone scan: most sensitive for early detection. Management Conservative treatment is mainstay: Activity modification/rest (“if it hurts, don’t do it”). Immobilization if needed for pain control. High-risk sites (femoral neck, navicular, 5th metatarsal) may require orthopedic referral or surgical fixation due to risk of nonunion. Address contributing factors: footwear, training errors, nutrition. QuestionAn 18-year-old female collegiate distance runner presents with 2 months of progressive shin pain that worsens with activity and is now present at rest. Exam shows focal tenderness along the mid-tibia. Radiographs are normal. She reports a recent increase in weekly mileage, low dietary calcium intake, and irregular menses. Which of the following factors most directly predisposes her to stress fracture?
