Answer:
289.1kg
Explanation:
because W=M*G, and M=W/G, so 2891N/10m/s²=289.1kg

Answer:
h = 384.4 m
t = 8.5 s
Explanation:
The firework will explode at the highest point. Because it would start to move downward at the highest point. Using 3rd equation of motion:
2ah = Vf² - Vi²
where,
a = acceleration due to gravity at that planet = -10.56 m/s²
h = maximum height = ?
Vf = Final velocity = 0 m/s (since, firework stops at highest point)
Vi = Initial Velocity = 90.1 m/s
Therefore,
2(-10.56 m/s²)(h) = (0 m/s)² - (90.1 m/s)²
<u>h = 384.4 m</u>
Now, we use 1st equation of motion:
Vf = Vi + at
0 m/s = 90.1 m/s + (-10.56 m/s²)(t)
<u>t = 8.5 s</u>
