Answer:
Distance travel s = 296.8 m
Explanation:
Given:
Initial velocity u = 6.5 m/s
Constant acceleration a = 2.1 m/s²
Time T = 14 s
Find:
Distance travel s
Computation:
s = ut + (1/2)at²
s = (6.5)(14) + (1/2)(2.1)(14)²
s = 91 + 205.8
Distance travel s = 296.8 m
Answer:
it is shifting from a planned a free-market economy
Answer:
20%
Explanation:
Efficiency of an engine is a ratio in percentage of the work done to the energy intake of the engine.
η=(q₁-q₂)/q₁×100%
η is efficiency, q₁ is the energy intake, q₂ is energy wasted.
the information provided is:
energy intake = 400 j
work done = 80 j = (400-320) =q₁-q₂
energy wasted =320 j
η= 80/400×100%
=20%
