1.) When a 1984 Alfa Romeo Spider sports car accelerates at the maximum possible rate, its motion during the first 20 s is extremely well modeled by the simple equation v2x=2Pmt where P = 3.6 × 104 W is the car's power output, m = 1200 kg is its mass, and vx is in m/s. That is, the square of the car's velocity increases linearly with time. a.) Find an algebraic expression for the car's acceleration at time t. Express...
