Question

Conceptual questions of cars on the road.
a) When we see a car go by on the highway at 120 miles / h we exclaim things like "That
car is really fast! ”, although in reality it is going with constant speed. Why if the
accelerator pedal is too tight, the car is not accelerated? Explain using the laws of
Newton.
b) Many times we think that what makes the car move is its engine. However, for very
powerful the motor (the energy it delivers per unit of time), the car cannot
move if you are on a mudrack, or on a puddle of fat. Is it the engine, or is the road what
what accelerates the car? Explain using Newton's laws.
