A 26-mH inductor, an 7.9-? resistor, and a 6.2-V battery are connected in series.The switch is closed at t = 0. Find the voltage drop across the inductor at t = 0. V
Bob (m = 60kg) is wearing a sticky suit. Just as he reaches his desired speed of 6m/s, he reaches the edge of ice (assume the ice is frictionless) and collides with a large crate (m = 250kg). How elastic was the collision
A box of ant aunts m1 = 1.65kg and a box of ant uncles m2 = 3.30kg, slide down an inclined plane while attached by a massless rod parallel to the plane. The angle of the incline is zeta = 30 degree. The cefficient of the kinetic friction between the ..
