8- Four seconds after being launched, what is the height of a ball that starts from a height of 12 m with an initial upward velocity of 24 m/s? 9- What is the average acceleration of a yocket that travels 400 m in 5 s if it starts from rest? 10- If the slope of a position versus time graph is decreasing, what does this indicate about velocity over time?

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
