A 1382-kg car is moving westward with a speed of 21.1 m/s, and a 2924-kg truck is traveling east with a speed of 16.0 m/s. Find the velocity of the center of mass of the car-truck system. Assume that the "positive" direction is to the east.
Calculate the centripetal force on the motorcycle.
An ac generator with a frequency of 1.44kHz and an rms voltage of 21.2V is connected in series with a 1.90 kiloohms resistor, What is the power factor for this circuit
A car is behind a truck going 25m/s on the highway. The car's driver looks for an opportunity to pass, guessing that his car can accelerate at 1.0m/s2. He gauges that he has to cover the 20-m length of the truck, plus 10m clear room at the rear of..
A thin, light wire is wrapped around the rim of a wheel, If the suspended object moves downward a distance of 3.40m in 1.86s, what is the mass of the wheel
A tank holds a layer of oil, of thickness To = 1.43 m, that floats on a layer of syrup of thickness Ts = 0.640 m, What is the index of refraction of the oil
Two circuits contain an emf produced by a moving metal rod, like that shown. The speed of the rod is the same in each circuit, other than the bulb in circuit 1 has one-half the resistance of the bulb in circuit 2.
