A train travels 63 kilometers in 2 hours, and then 56 kilometers in 3 hours. What is its average speed? i need the answer and un

kolbaska11 [484]

The average speed is the ratio between the total space and the total time of the motion:
$v= \frac{S_{tot}}{t_{tot}}$
The total space is
$S_{tot}=63 km + 56 km = 119 km$
while the total time is
$t_{tot}=2h+3h = 5h$
So, the average velocity is
$v= \frac{119 km}{5 h} =23.8 km/h
$

We can also rewrite it in m/s. The total space is $S_{tot}=119000 m$ , while the time is $t_{tot}=5h\cdot 3600 s/h = 18000s$ , and so
$v= \frac{119000m}{18000s}=6.6 m/s$

Can you make the work output of a machine greater than the work input?

drek231 [11]

Nearly equal the output work is greater than the input work because of friction.All machines use some amount of input work to overcome friction.The only way to increase the work output is to increase the work you put into the machine.You cannot get more work out of a machine than you put into it.
