Acceleration (a)= 5.71
Time= 15.46 seconds
1.) Through derivation, we will be able to determine that the formula for time is:
2.) Substitute the values:
3.) Through basic algebra, we will get this
1.) The basic formula for acceleration is:
2.) Subsitute the values
1.) Your question stated no initial velocity, only the final velocity
2.) The value we inputted for time is the one that we solved for in section A
3.) Solve for the answer
A radar in an airport detects that an airplane is 30.0km away from it. How long will it take a pulse of radio waves to reach the plane and return to the radar
Considering that the radio wave is travelling in a vacuum, its velocity is 300,000,000 m/s.
v (velocity) = 300,000,000 m/s
d (distance) = 30 km (back and forth is equal to 60 km)
60 km is equal to 60,000 m.
t (time) = unknown
we can use the formula v=d/t and to find to we use t= d/v
= 60, 000 m / 300,000,000 m/s
= 0.0002 seconds
it take a pulse of radio waves to reach the plane and return to the radar in 0.0002 seconds
