We would like to show you a description here but the site won’t allow us. Speed is ignorant of direction. two times the b. Multiply the masses, and multiply the result by the gravitational constant G = 6. Since the object's velocity at the top is 0 m/s, the average upward velocity during the trip up is one-half the initial velocity. The average speed is 12 km/h.
