Two cars with different masses are taking a left turn in a flat road. Which of those cars will experience a bigger (a) centripetal force? (b) centripetal acceleration?
Estimate the speed at which the drag on a 150 g steel ball becomes equal to about one percent of its weight. (The density of steel is about 7900 kg/m^3 and C for a sphere is about equal to 0.5.)
Vector a has a magnitude of 15 units and points die east. Vector b points due south. What is the magnitude of b if a-b has a magnitude of 25 units
An eagle with a wing span of 2.0m flies due north at 8.0m/s in a region where the vertical component of the earth’s magnetic field is 0.2x10-4 T. What emf would be developed among the eagles wing tips?
A car is driven east for a distance of 44 km, then north for 22 km, and then in a direction 26° east of north for 20 km. Determine the magnitude of the car's total displacement from its starting point
