Answer:
Part a)
Part B)
Explanation:
Part a)
Average power is rate of energy consumption
So it is given as
Part b)
If the efficiency is given as
%
so we know that 20% of total energy consumed is converted into output work
So total power consumed here will be given as
Energy consumed by him
now we know that 1 g fat will release 9 Calories energy
So we have
so to consume 1000 g of fat we need to release total energy
so total number of times
Answer:
5 N
Explanation:
The formula that you've to use to find the force is :
Force = Mass × Acceleration
They have already given that,
m = 2.5 kg
a = 2 ms⁻²
Let us find now.
F = m a
F = 2.5 kg × 2 ms⁻²
F = 5 N

Answer:
The initial velocity is 1.27 m/s.
Explanation:
distance, s = 1.8 m
acceleration, a = - 0.45 m/s^2
final velocity, v = 0
let the initial velocity is u.
