Answer:
Machine Efficiency
Explanation:
Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work). The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent

Answer:-600N
Explanation:
Mass(m)=1000kg
Initial velocity(u)=25m/s
Final velocity(v)=12.5m/s
Time(t)=22 seconds
v=u+axt
12.5=25+ax22
collect like terms
12.5-25=22a
-12.5=22a
Divide both sides by 22
-12.5/22=22a/22
-0.6=a
Acceleration=-0.6
Force=mass x acceleration
Force=1000 x -0.6
Force=-600
