a. x = Vo.cos 60. t
150√3 = 60. 1/2. t
t = 5√3 s
Waktu utk mengenai tembok 5√3 s.
b.
Vx = Vo.cos 60 = 60. 1/2
Vx = 30 m/s
Vy = Vo.sin 60 - g.t
Vy = 60.1/2.√3 - 10. 5√3
Vy = - 20√3 m/s ( arah kebawah )
V = √( Vx² + Vy² )
V = √(900 + 1200)
V = √2100
V = 45,8 m/s
c.
y = Vo.sin 60.t - 1/2.g.t²
y = 60.1/2.√3. 5√3 - 1/2.10.(5√3)²
y = 450 - 375
y = 75 m
Tinggi bola saat kena tembok 75 m
