b) Equal to 243 N.
Explanation:
The total force acting on the car in the opposite direction including the road friction and air resistance is equal to 243 N.
This is in conformity with newton's third law of motion.
Newton's third law of motion states that "action and reaction are equal and opposite in direction. "
- The action force is that of the pull by Harry acting on the car.
- The reaction force is in the opposite direction.
- Both action and reaction force equal and opposite and magnitude and direction

Explanation:
Para este ejercicio, debemos usar la segunda ley de Newton, donde se necesita fija un sistema de referencia el mas usado es un sistema horizontal y vertical para los ejes x e y
en el adjunto puede ver el diagrama de cuerpo libre correcto,
las fuerza son
Eje x
fr- F = m a
eje y
N-W =0
la ecuacion para la fuerza de roce es
fr = my N

Explanation:
Hence the above equation is balanced.
Answer:
Hello There!!
Explanation:
There is no work done against the force of gravity because the angle of displacement and the direction is 90°.
hope this helps,have a great day!!
