Answer
given,
height of Alpe d'Huez = 1100-m
time = 37.5 min
mass of the rider and his bike = 65 Kg
the metabolic power to ride = 700 W
U = m g y
U = 65 x 9.8 x 1100
U = 700700 J
since efficiency is 25%
b) 
P = 1245.68 W
Answer:
Monochronic.
Explanation:
This view is called as Monochronic.
The dictionary definition of Mono-chronic is that Monochronic people just like to do one thing at a time. They respect a certain uniformity and sense of being a suitable place and time for different activities. They don't esteem interruptions. It has been generally observe that their focus and productivity remains higher than the polychronic.( Those we are comfortable with performing multiple task at a time)
Kinetic energy = 1/2 m v²
If we reduce the mass by half > m/2
Kinetic energy = 1/2 m/2 v²
We should know that 1/2 × 1/2 = 1/4
So kinetic energy will be :
1/4 × m × v²
Answer:
22) 5.6 Kg.m/s
23) 0.067 Kg
24) 1.16 m/s
Explanation:
Momentum is found by multiplying mass and velocity
P=mv where P is momentum, m is mass of object and v is the velocity
22
Given
Mass, m=2 Kg
Rate, v=2.8 m/s
Relationship
P=mv
Solution
P=mv=2*2.8=5.6 Kg.m/s
23
Given
Momentum, p=0.1 Kg.m/s
Rate, v=1.5 m/s
Relationship
P=mv and making m the subject then
Solution
24
Given
Momentum, 
Mass, 
Relationship
P=mv and making v the subject then
Solution
Answer:
69.42 m
Explanation:
From the question given above, the following data were obtained:
Initial velocity (vᵢ ) = 4.9 m/s
Acceleration (a) = 4.2 m/s²
Time (t) = 4.7 s
Displacement (Δx) =?
Thus, we can obtain the displacement by using the following formula:
Δx = vᵢt + ½at²
Δx = (4.9 × 4.7) + (½ × 4.2 × 4.7²)
Δx = 23.03 + (2.1 × 22.09)
Δx = 23.03 + 46.389
Δx = 69.419 ≈ 69.42 m
Thus, the distance travelled is 69.42 m
