It is false that as <span>you watch an airplane fly above you, the angle of elevation to the airplane gets closer to 0° as the airplane approaches the point directly overhead.
As a matter of fact, it gets closer to 90</span>°. When the plane is far away, then it is closer to 0. But since it is overhead, it is almost exactly 90°.
The equation v²=u²+2as will help with solving this equation
v is what we are trying to find
u=0
a=4.9
s=200
v²=0²+2*4.9*200
v=√(2*4.9*200)
v=√1960
v=44.3 m/s (3 sf)
Using Dimensional analysis
15min/1·1hr/60min
15/1·1hr/60=15/60hr
.25hr
.25hr·12.5Km/h=3.125Km
Answer:
<h2>10 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 5
We have the final answer as
<h3>10 N</h3>
Hope this helps you
13 is the mode because it is the number that appears most often
