The air speed indicator of a plane that took off from Detroit reads 343 km/h and the compass indicates that it is heading due east to Boston. A steady wind is blowing due north at 38.3 km/h.
a) Calculate the speed of the plane with reference to the ground.
b) If the pilot wishes to fly directly to Boston (due east) what must the compass read? (0 = North, 90 = East, ...)
Two point charges 2.4 and 6.50 are 0.10 apart. Point is midway between them; point is 8.00×10-2 from and 6.00×10-2 from . Take the electric potential to be zero at infinity. Find out the work done by the electric field on a charge of 2.50 that tra..
a 1340-kg car has just passed a diner. The closest the car came to the diner was R=16.5m, but the car has driven another x=22.7m in the 2.05 seconds elapsed since then. what is the current magnitude of the anguar momentum of the car
