Answer: 3.886 m/s
Step-by-step explanation:
1 A.
The initial velocity (u) = 10 km/hr or 2.77 m/s
1 B.
The final velocity (v) = 60 km/hr or 16.66 m/s
1 C.
5 seconds.
1D. Acceleration = Final velocity - initial velocity / time
= 16.66 m/s - 2.77 m/s / 5 s
= 3.886 m/s.
Answer:
48
Step-by-step explanation:
2^2-1 = 3
3^2-1 = 8
4^2-1 = 15
so on so fourth
7^2-1 = 48
Answer:
7 seconds
Step-by-step explanation:
SA = 4πr²
784π = 4πr²
196 = r²
r = 14
At 2 cm/s, it takes 7 seconds to reach a radius of 14 cm.
