2) The 2000 Belmont stakes winner, Commendable, ran the horse race at an average speed of 15.98 m/s. If Commendable and
jockey Pat Day had a combined mass of 550.0 Kg, what was
their KE as they crossed the finish line?

Astudent pushes a 60-n block across the floor for a distance of 10 m. how much work was done to move the block

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)
