Thank you so much!

Doc Al - thanks for your patience. I do understand now and I can sleep soundly.

Did you get my last question?

What about the truck? Will it hit the Volkswagen with equal opposite reaction?

I can understand when a vehicle hit a wall. The vehicle will have an equal and opposite reaction equal to the force of the car.

I am really thick headed. I am talking about the force. Won't the truck hit the volkswagen and push the latter?

Please bear with me. Suppose the truck has a force of 1000 lbs and the Volkswagen has 100 lbs. Please tell me the net force of the system. Also, will the truck have an opposite reaction of 1000 lbs? And the Volkswagen 100lbs?

My difficulty is this: I know that the Volkswagen will move with more acceleration after the impact because of it's smaller mass. But, I am always thinking of the second law of motion (F=ma), how do we determine the resultant force for the two vehicles? Doc Al - thanks for being there...

Momentum Problem: A large truck and a Volkswagen have a head-on collision. Which vehicle experiences the greatest force of impact? Answer: Both the Volkswagon and the large truck encounter the same force. Does it mean that the magnitude of force is the same for both vehicles? I am...

thanks, that's it. It is nice to have a person like you always ready to help!

Another way of solving, which I am not sure is: d =volt + (0.5)at^2 50= (-15)t + 16.1 t^2 t= 2.28 seconds

or is it 3 seconds, now I am guessing.

Is the following correct: -50 = volt -32.2/2(t^2) -50 = 15t -16.1t^2 t = 2.28

I can only solve for the height after 2 seconds which is 15.6 ft, but I do not know how to solve for the total time.
