Answer:
2.57 s
8.12 m
46.4 m
Step-by-step explanation:
1. In the y direction:
s = 0 m
u = 22 sin 35° m/s = 12.6 m/s
a = -9.8 m/s²
Find: t
s = ut + ½ at²
0 = (12.6) t + ½ (-9.8) t²
t = 2.57 s
2. In the y direction:
u = 12.6 m/s
v = 0 m/s
a = -9.8 m/s²
Find: s
v² = u² + 2as
0² = (12.6)² + 2 (-9.8) s
s = 8.12 m
3. In the x direction:
u = 22 cos 35° m/s = 18.0 m/s
a = 0 m/s²
t = 2.57 s
Find: s
s = ut + ½ at²
s = (18.0) (2.57) + ½ (0) (2.57)²
s = 46.4 m
