What is the impulse on a 45,000 kg airplane when it changes its velocity from 242 m/s to 258 m/s?*

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.)

If it takes a planet 2.8 x 10^8 s to orbit a star with a mass of 6.2 x 10^30 kg what is the average distance between the planet and the star

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?
