Answer:
40m/s
Explanation:
a=g
u=0
s=81
v²=u²+2as
v²=2(9.81)(81)
v=√1587.6=39.8446985181≈40m/s
Answer:
27.3 meters
Explanation:
A train travels up a hill that is 100 meters long. If the train has climbed 50 meters vertically, it traveled 27.3 meters vertically. Therefore, the answer is 27.3 meters.
(100)² = (50)²+x²
10000 - 2500 = x²
7500 = x²
x = 27.3 or 27.3 meters
Hope this helped!
