The range of a projectile fired at an angle with the horizontal and with an initial velocity of feet per second is where r is measured in feet. A golfer strikes a golfball at 115 feet per second. Ignoring the effects of air resistence, at what angle must the golfer hit the ball so that it travels 120 feet? (Round answer to nearest angle.) Question 13 options:

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)
