The projectile motion of an object can be modeled using Which solution can be simplified to determine when the h(t) = =gt2 + vot + ho, where g is the acceleration due to object will hit the ground? gravity, t is the time since launch, h(t) is the height of the projectile after time t, vo is the initial velocity, and ho is Of= -20 + (20)- - 4(4.9)(60) 2(4.9) the initial height. The acceleration due to gravity is -9.8 m/s2 O t= 60 + (60) - 40-4.9)(20) An object is launched at an initial velocity of 20 meters 2(-4.9) per second and an initial height of 60 meters. t= -20+ (20)2 - 40 4.9)(60) 2( -4.9) Ot= - 20 1 /(20)2- 4( 4.9)(-60) 2( 4.9)
