Answer:
It will take time=7.963 hours to completely discharge
Explanation:
The energy available in the battery is:
Energy stored=Power×Time
Energy stored=(ΔV)I×t
Energy stored=(12.0V×43.0A.h)
Energy stored=516 W.h
The two headlights together consume a total power of:
So the time required to completely discharge is:
It will take time=7.963 hours to completely discharge
Answer:
Dy = 111.66 [m]
t = 3.5 [s]
Explanation:
To solve this problem we must use the equations of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity = 27 [m/s]
g = gravity acceleration = 9.81 [m/s²]
t = time = 3.5 [s]
Note: The negative sign of the equation means that the gravity acceleration goes in opposite direction
Vf = 27 - (9,81*3,5)
Vf = - 7.33 [m/s] (this negative sign indicates that at this moment the snowball is going downwards)
To find how high the snowball was we must use the following equation:
Dy = (27*3.5) + (0.5*9.81*3.5)
Dy = 94.5 + (17.16)
Dy = 111.66 [m]
