Answer:
-75.35°
Explanation:
Let C be the sum of the two vectors A and B. Hence, we can write the following
but since the vector C is in the -y direction, = 0 and
= —12 m.
Thus
similarly, we can determine by rearranging equation (1)
so the magnitude of B is
Finally, the direction of B can be calculated as follows
Ф=
hence the vector B makes an angle of 75.35 clockwise with + x axis
Answer:
The tangential velocity for the cars are approximately 2.3 m/s
Explanation:
The given parameters are;
The radius of the Texas Star Ferris wheel, r = 65.8 mete secondsrs
The time it takes the Ferris wheel to go round once = 180 seconds
The angular velocity, ω = Change in angle rotated/(Time duration of the change)
ω = Δθ/Δt = 2·π/180
The tangential velocity for the cars, = ω·r = 2 × 3.14/180 × 65.8 ≈ 2.3 m/s
The tangential velocity for the cars, ≈ 2.3 m/s.
