For the first one I think B and for the third one it is D hope that helps
Dan had 52
shown work: 29 x 2=58 58-6=52
You would expect
to be increasing to the left of
, and decreasing to the right, which corresponds to
being positive when
(but near
) and negative when
.
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.
1)4
2)5
3)15
4)9
5)
The absolute value of a number describes its magnitude, or the distance a number is from zero when
placed on a number line
so |-2| = 2
