Acar travelling at 45 mi/hr (20.1 m/s) comes to rest in 4 seconds. find the acceleration of the car in m/s2.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

Acar drives toward the right over the top of a hill, as shown below. which arrow represents the centripetal acceleration? w x y z

Most short-period comets do not have randomly oriented orbits because
