when you carry the 2 and add the 3 its Z
Answer:
the answer is fulcrum because
Explanation:
lever is a simple machine consisting of a bar that rotates around a fixed point. The fixed point of a lever is called the fulcrum. Like other machines, a lever makes work easier by changing the force applied to the machine or the distance over which the force is applied
25,000 Feet = 7620m
PE = mgh where m is mass, g is gravity accel: 9.8 n h is height
= 90 x 9.8 x 7620
= 6720840J
= 6.72MJ
F = ma where m is mass, a is accel = gravity = 9.8
= 90 x 9.8
= 882N
Accel = gravity = 9.8m/s^2
KE = 1/2mv^2 where m is mass n v is vel
if no wind resistance, PE leaving airplane = KE at net
6720840 = 1/2 x 90 x v^2
v^2 = 149352
v = 386.5m/s
150MPH=67m/s
@150MPH, his speed is not changing so accel=0
accel=0, force=0 by newton's second law
force=0 when wind resistance = gravity = 9.8m/s^2
by conservation of energy, Luke's KE = PE = mgh = 6720840J
he was unhurt cuz' his momentum was absorbed by the net
Answer: lamda max= 16,5m lamda min= 0,0165m (air)
lamda max= 75m, lamda min=0,075m (water)
