Shortly after Ms. Berndt’s cat, Revere, was born, Ms. Berndt realized Revere wasn’t eating enough. She went to the pet store and bought many different kinds of food and fed Revere different types every day. Each day she noted the type of food and how much Revere ate out of his dish. Eventually Revere ate a lot of the Creppy Cat brand food and Ms. Berndt bought that for him from then on. Revere is the best worst cat ever.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
