Answer:
9x - 45
Step-by-step explanation:
9 * x = 9x and 9 * -5 = -45. Therefore the answer is 9x - 45

Answer:

Step-by-step explanation:
given,
angular deceleration, α = -0.5 rad/s²
final angular velocity,ω_f = 0 rad/s
angular position, θ = 6.1 rad
angular position at 3.9 s = ?
now, Calculating the initial angular speed




now, angular position calculation at t=3.9 s



Hence, the angular position of the wheel after 3.9 s is equal to 5.83 rad.
Answer:
t = (A/sx) - r
Step-by-step explanation:
Solve for t like this:
