In a vehicle safety test, a 1 580 kg truck travelling at 60.0 km/h collides with a concrete barrier and comes to a complete stop in 0.120 s. The magnitude of the change in the momentum of the truck, expressed in scientific notation, is b × 10w kg.m/s. The value of b is __________. (Record your three-digit answer in the numerical-response section on the answer sheet.) 1 Use the following information to answer the next question. At a coal mine, a train engine bumps an empty hopper car that has a mass of 1.00 × 104 kg such that it rolls at a constant speed of 2.00 m/s under a coal storage bin. When the hopper car triggers an electromagnetic switch on the track below the storage bin, the bin drops a load of 1.20 × 104 kg of coal into the hopper car. Cross section of coal storage bin Hopper car 4 m = 1.00 × 10 kg v = 2.00 m/s Numerical Response 3. The speed of the hopper car immediately after receiving the load of coal, expressed in scientific notation, is b × 10–w m/s. The value of b is...
