1. Riaz runs at 3 m/s with the football for 50 seconds. How far does he run?

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

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)

Five structural isomers have the formula c6h14. where needed, draw the structure and give the iupac name of all five isomers.
