Anewspaper is tossed at an angle of 35° above the horizontal. if it has a mass of 2.2 kg and a speed of 6 m/s, what is the magnitude of the momentum in the horizontal direction? a. 7.6 kg-m/s b. 10.8 kg-m/s c. 13.2 kg-m/s d. 34.1 kg-m/s

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)
