Asmall car gets into a head on collision with an 18­wheeler. during the collision, which vehicle has a larger magnitude force acting on it? during the collision which vehicle’s acceleration has the larger magnitude? explain your answers.

a) no vehicle has a larger magnitude force acting on it.

b) The vehicle's acceleration that has the larger magnitude will be the lighter one, the small car.

Explanation:

If we assume that during the collision there are no external forces acting on both vehicles (due to the very short collision time), the only forces acting are those due to Newton's 3rd Law, which by definition, are equal and opposite each other, one due to the car on the 18wheeler, and the other caused by the 18wheeler to the car.

So, as both forces are equal and no vehicle has a larger magnitude force acting on it.

Now, applying 2nd Newton's Law to each vehicle, it must be true the following:

F₁₂ = F₂₁  ∴ m₁a₁ = m₂a₂.

where m₁ = car mass   m₂= 18wheeler mass.

As m₁ is much much smaller than m₂, it follows that a₁ will be greater than a₂.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
