Explanation:
We have,
Mass of an automobile is 1150 kg
The automobile traveling at 86 km/h and then it comes to stop.
86 km/h = 23.88 m/s
It is required to find work done by the automobile.
Concept used : Work energy theorem
Th change in kinetic energy of an object is equal to the work done by it. The work done is then given by :

Here, v = 0

or

Therefore, the work done by the automobile is
.
If the potential energy of the three-object system is to be a maximum (closest to zero), should object 3 be placed closer to object 1, closer to object 2, or halfway between them?
If the potential energy of the three-object system is to be a maximum (closest to zero), should object 3 be placed closer to object 1, closer to object 2, or halfway between them?
Object 3 should be placed closer to object 1.
Object 3 should be placed on a halfway between object 2 and object 1.
Object 3 should be placed closer to object 2.
Solution
I think that Object 3 should be placed closer to object 2.
Velocity is correct, the symbol for acceleration is a. That is all I know.
(As in f=m*a)
If a food worker realizes that food is being kept at the incorrect temperature, he or she should immediately report it to their manager and politely request the customer to allow them some time to remake their order because it has been messed up.
The USFDA requires that hot foods should be held at 57 °C (135 °F) or above in order to ensure safety.
