Recall that
where and
are the lion's initial and final vertical velocities,
is its acceleration, and
is the vertical displacement.
At its maximum height, the lion has 0 vertical velocity, so we have
where <em>g</em> is the acceleration due to gravity, 9.80 m/s², and we take the starting position of the lion on the ground to be the origin so that .
Let <em>v</em> denote the initial speed of the jump. Then
Answer:
Power P=246.78 KW
Explanation:
Mass of Elevator=4710 Kg
Can carry load =1910 Kg
Total Mass m to be lifted =4710 kg + 1910 Kg =6620 kg
speed = 3.80 m/s ⇒ per second distance traveled (height h) = 3.80 m and time t = 1 s
Using formula of Power P =
P =
P= 6620kg × 9.81 m/s² × 3.80 m / 1s
P= 246780.36 W
P=246.78 KW
