The third one sliding friction
Explanation:
Answer:
θ = (7π / 3) rad
Explanation:
given,
displacement of simple harmonic motion along x-axis
equation is given as
x = 5 sin (π t + π/3 )
general equation of simple harmonic motion
x = A sin θ
θ is the phase angle
θ = π t + π/3
at t = 2 s


Phase of the motion at t =2 s is θ = (7π / 3) rad
Answer:
i dont know the answer for this question sorry for the misunderstanding
Explanation:
Answer:
30m/s^2
Explanation:
Acceleration=Final Velocity-Initial Velocity/Time
10m/s^2= Final Velocity-0m/s/3
30m/s^2= Final Velocity
Final Velocity=30m/s^2
Answer:
α = 1.875 rad/s²
t = 8 s
Explanation:
α = ω²/2θ = 15²/(2(60)) = 1.875 rad/s²
t = ω/a = 15 / 1.875 = 8 s
