Answer:
F = - 59.375 N
Explanation:
GIVEN DATA:
Initial velocity = 11 m/s
final velocity = 1.5 m/s
let force be F
work done = mass* F = 4*F
we know that
Change in kinetic energy = work done
kinetic energy =
kinetic energy = = -237.5 kg m/s2
-237.5 = 4*F
F = - 59.375 N
Answer:
So No of slices to be consumed by each person = n = 65
Explanation:
Energy released by one slice = E1
h = 8850 m ; m = 79 kg ,η= 10.5%
We know that potential energy given as
u = m g h
u = 79 x 9.81 x 8850
we know from the defination of efficiency that, η= E(out)/E(in)
Now amount of PE has to be compensated, In our case, E(out) =u
Let n be the number of bread slices to be consumed.
n = E(in)/E1
n=64.76
So No of slices to be consumed by each person = n = 65
