Answer:
The small car and the truck experience the same average force.
Explanation:
The average net force will be the resultant force of the average forces of both vehicles. On collision, they'll both experience the same impact force, but the deceleration and deformation felt by the individual vehicle will be proportional to the mass of the vehicle. This is why it will seem like the car will have more force but is not actually so.
Answer:
the Power required is 300 W
Explanation:
We know that the definition of work is given by the following expresion:

the distance is 1.5 meters and the Force is equal to 1000 N.
Replacing this values in the work expresion

And the power is equal to the amount of work done in a given time, therefore we have:

Time in seconds

Answer:
if I'm not wrong, 0 Joules
Explanation:
If it is not being moved at all, then no work is being done
