It'll last 20 hours. If it travels 110 miles in one hours, 110 times 20 equals 2,200.
Answer:
Height of cliff = S = 20 m (Approx)
Explanation:
Given:
Initial velocity = 8 m/s
Distance s = 16 m
Starting acceleration (a) = 0
Computation:
s = ut + 1/2a(t)²
16 = 8t
t = 2 sec
Height of cliff = S
Gravitational acceleration = 10 m/s
S = 1/2a(t)²
S = 1/2(10)(2)²
Height of cliff = S = 20 m (Approx)
Answer:

Explanation:
From the conservation of mechanical energy




Solve to velocity v2




I'd say B.) Increasing the voltage of the battery.
