Answer:
False
Explanation:
Mercury has 0 natural satellites.
Average speed = (total distance covered) / (time to cover the distance)
Total distance = 69 km + 51 km = 120 km
Total time = 3 hrs + 2 hrs = 5 hrs
Average speed = (120 km) / (5 hrs) = 24 km/hr
To calculate the horizontal distance traveled by the ball, we first calculate the total time it takes to reach the ground as follows:
t = √[2y/g] = <span>√[2(0.55) / 9.81]
t = 0.33 s
The horizontal distance would be
</span><span>X = Vx*t = 1.2*√[2*.55/9.8] = 0.4 m
</span>
Hope this helps.
