... A 263-g block is dropped with an initial speed such that it hits onto a vertical light spring of force constant k = 2.52 N/cm. The block sticks to the spring, and the spring compresses 11.8 cm before coming momentarily to rest. While the spring is being compressed, how much work is done (a) by the f ...

Knowing that you need to leave 100 ft when traveling at 30 mph to stop, you figure that you can leave 200 ft between you and the next car if you are going 60 mph…in case you need to suddenly stop. The truck in front of you suddenly stops to avoid an a ...
