Does it not tell you how long it took it to reach the ground? Constant Velocity should be distance over time
Answer:
<u><em>3 hours</em></u>
Explanation:
If the car takes 2 hours to go 40 miles, then the car can go 20 miles in 1 hour. Since the car is going 60 miles, it will take 3 hours.
Hope that makes sense :)
The answer is D because i'm in the same studies right now.
Answer:
7.1 m/s
Explanation:
First, find the time it takes for the fish to reach the water.
Given in the y direction:
Δy = 6.1 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
6.1 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 1.12 s
Next, find the velocity needed to travel 7.9 m in that time.
Given in the x direction:
Δx = 7.9 m
a = 0 m/s²
t = 1.12 s
Find: v₀
Δx = v₀ t + ½ at²
7.9 m = v₀ (1.12 s) + ½ (0 m/s²) (1.12 s)²
v₀ = 7.1 m/s
