Answer:
a)5m b)5secs c) 10secs
Explanation:
a) maximum height H = u²/2g
Given u = 50m/s
g = 10m/s²
H = 10²/20
H= 5m
maximum height reached by the rocket is therefore 5m
.b)Time it takes the rocket to reach its maximum height is Tmax = U/g
Tmax = 50/10
Tmax = 5seconds
c) How long the rocket spent in the air is the time of flight T
T = 2U/g
T = 2×50/10
T = 100/10
T = 10seconds
Answer:
2.943 J
Explanation:
Data:
acceleration due to gravity, g = 9.81 m/s²
mass of sand = 0.5 kg
distance = 0.6
Thermal energy = the energy possessed by the falling sand
The force of sand = ma
= 
However, the energy is given as the force multiplied by the distance, so
E =fd

Therefore, the thermal energy is 2.943 joules
Answer:
OHHH.. I know what you talking about.
Explanation:
Okay so Netforce escape room is a Game on the playstore app and every time you type the code in it unlocks the door and you move up to different levels.
Explanation:
Average velocity = displacement / time
v = (25 m − 2 m) / 4.5 s
v = 5.11 m/s
