CAN SOMEONE PLEASE HELP ME!! 6. It takes a minimum force of 280 N to move a 490 N crate. What is the coefficient of static friction between the crate and the floor?

7. If two 882 N passengers get in a 294 N sled, how much force will the puller have to exert to
move the sled? The coefficient of maximum static friction between the sled and the snow is
0.150.

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)
