Where is the following steps??
Answer:
Total change in energy = 31 KJ.
Explanation:
Mass m=25 kg
Height h = 1 m
Initial velocity = 0
Final velocity = 50 m/s
Energy at initial condition
Energy at final condition
So the change in energy = 31250 -250 J
The total change in energy = 31000 J
Answer:
no need for that
Explanation:
they are not the same at all
Answer:
FCW in car stands for <em>Forward Collision Warning.
