Question: A car rounds a 1.45 km radius circular track at 95 km/h.
Part A: Find the magnitude of the car's average acceleration after it has completed one-fourth of the circle.
Please show all work to find the magnitude of the car's average acceleration.
What is the terminal speed of a 5.6 kg spherical ball with a radius of 3.0 cm and a drag coefficient of 1.55? The density of the air through which the ball falls is 1.2 kg/m3
Suppose that the voltage of the battery in the circuit is 3.3 V, the magnitude of the magnetic field (directed perpendicularly into the plane of the screen) is 0.66 T, and the length of the rod between the rails is 0.23 m. Assuming that the rails are..
