The angular position of a small sphere welded on a spinner wheel is given in the graph below. Calculate the angular velocity at t = 3 s and t =10 s
at t = 3 s , ω = 0.84 rad/s ; at t = 10 s , ω = 0.84 rad/s
at t = 3 s , ω = 1.26 rad/s ; at t = 10 s , ω = 0 rad/s
at t = 3 s , ω = 1.26 rad/s ; at t = 10 s , ω = 0.68 rad/s
at t = 3 s , ω = 31.4 rad/s ; at t = 10 s , ω = 62.8 rad/s
