acceleration a = v - u / t = 25 - 13 / 6 = 2 m/s^2
so that distance travelled S = v^2 - u^2 / 2 a = 25 x25 - 13 x13 / 2 x 2 = 114 m.
Answer:
C
Explanation:I took the test
Answer:
2y=8-x
y-2x=-1
y-2x=-1
y = 2x-1
Substitute for y in the 1st
2(2x-1)=8-x
4x-2=8-x
5x = 10
x = 2
y=2x-1
y = 3
Explanation:
2y=8-x
y-2x=-1
------------
Rearrange:
x = 8-2y
y = 2x-1
------------
Substitute to get:
y = 2(8-2y)-1
y = 16-4y-1
5y = 15
y = 3
-------------------
Substitute to solve for "x":
x = 8-2(3)
x = 2
Answer:
On 14 August a typhoon destroyed most of the Mongol fleet, wrecking ships that had been tied together for safety against Japanese raids and smashing the uncontrollable vessels against the coastline. From half to two-thirds of the Mongol force was killed.
