Answer with Explanation:
We are given that
A=3i-3j m
B=i-4 j m
C=-2i+5j m
a.
Compare with the vector r=xi+yj
We get x=2 and y=-2
Magnitude= units
By using the formula
Direction:
By using the formula
Direction of D:
b.E=-A-B+C

Direction of E=
Answer:
attached below is the free body diagram of the missing illustration
Initial kinetic energy of the electron = 3 eV
Explanation:
The conclusion that can be drawn about the kinetic energy of the electron is
E = initial kinetic energy of the electron
E = -4 eV
E = -1 eV
insert the values into the equation above
= -1 -(-4) eV
= -1 + 4 = 3 eV
Answer:
It should fly 8° to west of south at 430km/h
Explanation:
According to the diagram. X components for both velocities must have the same magnitude in order to get the resultant velocity due south.
Solving for α:
α = 8.03°
