46. A police officer in hot pursuit drives her car through a circular turn of radius 300 m with a constant speed of 80.0 km/h. Her mass is 55.0 kg.What are (a) the magnitude and (b) the angle (relative to vertical) of the net force of the officer on the car seat? (Hint: Consider both horizontal and vertical forces.) I don't understand why the net force in the problem is centripetal force and gravitation. I think there should be normal...

6. A motor car, of a total mass 1400 kg, running in top gear at 55 km/h, passes on to a rsing gradient of 1 in 20 at that speed. The road and other resistances may be taken as constant at 270 N/t. With condition unchanged, the speed falls uniformly to 40 km/h in a distance of 360 m. An intermediate gear is then engaged for which the speed ratio between the engine and the road wheels is 9:1 and...

A circular loop of radius 1.79 m is mounted on top of a truck. Initially the truck is at rest oriented so that a vector normal to the loop points north. At this location, the Earth’s magnetic field has a magnitude of 49.6 μT and a direction of due north, 63° below the horizontal. Over the course of 9.0 seconds, the truck accelerates north, so that at the end of the time interval, the truck is moving at 14.0 m/s...

A car travelling at 3.0 m/s drives into an empty parking space. At the same instant, a truck that has an inertia 50% greater than the car’s is using the same parking space to take a shortcut through the parking lot. Both vehicles are coasting (zero acceleration conveniently), and just before they hit head-on, the truck is moving at 4.0 m/s. During the collision 75% of the initial KE of the car-truck system is converted to internal energy. There are...
