Answer:
A True. It agrees with Newton's third law
3 True. The car pushes the truck and goes at constant speed
Explanation:
To examine the final answers, we must silver the solution of the problem, if we see Newton's third law, action and reaction, we see that the car pushes the truck the action, the truck must oppose this force with a force applied on the car of equal magnitude, but opposite direction
In view of the above, let's review the statements.
A True. It agrees with Newton's third law
B False. Violate Newton's third law
C False violate Newton´s third law
D False. The force is exerted by the car not specifically by the engine
E Faults if no force is exerted the truck should stop due to friction
Second question
If the two vehicles move at the same speed, the resulting force on each of them must be zero
1 False. If the truck doesn't get nine, it can't go at cruising speed
2 False if the car is accelerating it cannot go at constant speed
3 True. The car pushes the truck and goes at constant speed
4 False. If the truck slows it should slow down
