Answer:
10.895 m
Explanation:
v = Velocity
g = Acceleration due to gravity = 9.81 m/s²
h = Height of waterfall = 5 m
Distance traveled by an object which has forward velocity is given by
The distance between them is 25.75181-14.85681 = 10.895 m
Answer:
F=75.53N
Explanation:
To calculate the power we define the equation,
Where,
F= Force
V= Velocity,
Here we have that 2.43hp is equal to 1812.78W,
clearing F,

Answer:
L = 4.58 x 10⁴ kg.m²/s
Explanation:
The angular momentum is given by the formula:
L = mvr
but, v = rω
Therefore,
L = mr²ω
where,
L = Angular Momentum of the person = ?
m = mass of person = 99 kg
r = radius of earth = 6.37 x 10⁶ m
ω = Angular Speed of Earth's Rotation = θ/t
Since, earth completes 1 rotation in 1 day. Hence,
ω = (2π rad/1 day)(1 day/24 h)(1 h/3600 s)
ω = 7.27 x 10⁻⁵ rad/s
Therefore,
L = (99 kg)(6.37 x 10⁶ m)²(7.27 x 10⁻⁵ rad/s)
<u>L = 4.58 x 10⁴ kg.m²/s</u>
