Amsterdam, February 2006. Wednesday morning, 9 AM, a large beer truck, full of beer, was driven onto the market square shown above. The driver of the truck suddenly felt the ground moving. “It just looked as if there was an earthquake”, he said. There was a tear of more than 10 meters in roof of the parking garage below and people were afraid that the parking garage would collapse. The truck could only be removed when the floor on which the truck was standing had been reinforced with supporting beams.

As a result of this an independent investigation will take place. Assume you have graduated and are part of the investigating team. What questions would you ask and what information would you require in order to recommend the best course of action?

A helicopter is moving horizontally at 90 km.p.h. at a height of 200 m towards a target on the ground,

which is intended to be shelled, Estimate the distance from the target , where the shell must be released in

order to hit the target.

Also find the velocity with which the shell hits the target and the direction of shell at the time of hitting

the target.
