Answer:
<u>A kangaroo hops 60 m to the east in 5 s. What is the kangaroo's average velocity? ... The kangaroo stops at a lake for a drink of water and then starts hopping again to the south. Each second, the kangaroo's velocity increases 2.5 m/s.</u>
Yes it is possible to add sound to a system to make it quieter
Answer:
10512m
Explanation:
Using formula for Uniform Velocity v = D/t ;
where v = Velocity (367 m/s); D = Vertical distance (?); t = length of time of motion (?).
To find t we use the Kinematic equation D= v₀t + (1/2(at²));
where D = Distance traveled (4020m); v₀ = initial velocity (0); a = acceleration;
4020 = (0)t + (1/2(9.8)t²)
4020 = 1/2(9.8)t²
t² = 4020/(1/2(9.8))
t = √(4020/4.9).
back to our formula for Uniform Velocity v = D/t;
D = vt
D = (367)(√(4020/4.9))
D ≈ 10512m
