Why was an asteroid with only a 10-15 km (7-8 mile) width able to wipe out the dinosaurs and cause the extinction of 75% of all species on Earth?

That width is less than the distance I drive from my house to the grocery store. Why was that size of an asteroid able to cause such catastrophic damage?

Imagine an explosion so big that it is able to instantly vaporize both your house and your grocery store and turn all the air into super hot plasma. Just imagine how much destruction that would cause on the rest of the city and surrounding area. That is what happens when a meteor hits the atmosphere. But unlike an explosion which only takes a fraction of a second the meteor will continue to output that amount of energy all the way down through the atmosphere for minutes sending out shock waves and super hot plasma in all directions. And that is only as it descends down the atmosphere. When it hits the ground the impact is going to cause even bigger shock waves through the earth and turn the bedrock into hot magma. It will force the earth to bend out of the way from the impact. Your house and grocery store would only be at the center of the devastation, the bedrock under your feet would need to go somewhere, and the rocks it displaces would need to go elsewhere.
