Closest one is A. “The largest Vehicle”
Answer: 12.4 feet
Explanation:
If there is a smooth transition and there is no change in slopes, energy considerations can be used
The cube has a kinetic energy of
ke = mv^2/2 = 10 lbm * 20^2ft^2/s^2 / 2 = 2000 lbm-ft^2 / s^2
At the highest point when there is a gain in potential energy
pe = mgh = 10 lbm * 32.2 ft/s^2 * h ft = 322 lbm ft^2/s^2
If there is no loss in energies,
pe = ke
322h lbm ft^2/s^2 = 2000 lbm ft^2/s^2
h = 2000 /322 = 6.211 (ft)
= h / sin(30) = 12.4 ft
Answer:
175.99.136.0
Explanation:
175.99.138.0/21
Step 1: convert both the ip and the subnet mask to binary format
175.99.138.0 - 10101111.1100011.10001010.00000000
/21 : 255.255.248.0 - 11111111.11111111.11111000.00000000
step 2: perform the bitwise AND operation
In an AND operation, a result of 1 can only be gotten when both inputs are 1. Otherwise, the result will be 0.
10101111.1100011.10001010.00000000
11111111. 11111111. 11111000. 00000000
------------------------------------------------------
10101111. 1100011. 10001000. 00000000
step 3: convert the binary result back to base 10 number
10101111. 1100011. 10001000. 00000000
175.99.136.0
