Answer:
10.16 minutes
Explanation:
14 min 34.56 s = 14*60 + 34.56 = 874.56 seconds
The speed of record swimming is distance over time
v = 1500 / 874.56 = 1.715 m/s
0.65 miles = 0.65 * 1609 = 1045.85 m
The time it takes to swim 0.65 miles (1045.85 m) at the rate of 1.715 m/s is
t = s/v = 1045.85 / 1.715 = 609.77 s or 609.77 / 60 = 10.16 minutes
Answer:
a) v₀ = 39.83 v / s
, b) y = 111.94 m
Explanation:
a) Let's use the kinematic relations for this problem
v² = v₀² - 2 g y
The speed at the base of the cliff is 30 m / s, the height y = 31 m
v₀² = v² + 2 g y
v₀ =√ (30² + 2 9.8 31)
v₀ = 39.83 v / s
b) at the point of maximum height the speed is zero
0 = v₀² - 2 g (y –y0)
y = y₀ + v₀² / 2g
.y = 31 + 39.83²/2 9.8
y = 111.94 m
