Answer:
(a) 4 rad/s^2
(b) 18 rad
Explanation:
w0 = 0, w = 12 rad/s, t = 3 s
(a) Let α be the angular acceleration.
w = w0 + α t
12 = 0 + 3 α
α = 4 rad/s^2
(b) Let θ be the angle rotated
θ = w0 t + 1/2 α t^2
θ = 0 + 0.5 x 4 x 9
θ = 18 rad
Answer:
b) The gravitational pull will be weak.
Explanation:
Less mass requires less force. Gravity or gravitational pull is a force. In order for you to stay in place and not go through the ground, however, you require something to pulling you away from the Earth. That's why we have air resistance.
Answer:False
Explanation:The Earth rotates faster at the equator than at the poles.
