Question

The planet Venus rotates at an extremely slow rate, making one rotation (in the opposite, or retrograde, direction compared to other planets) every 246 Earth days.

One science fiction idea to spin Venus up is to attach massive rockets to the surface of the planet to increase its spin rate. Assume such rockets are able to apply a tangential acceleration of g = 9.8 m/s2.

Venus up from essentially zero rotation to a rotation rate similar to the Earth? The radius of Venus is about 6,052 km.

Answer 1

We are given,
The tangential acceleration to be applied at the surface of Venus
Initial rotation speed of the Venus
Radius of Venus
Radius of Venus

Earth's linear rotation speed at the equator is .

Therefore, the angular rotation speed of the Earth can be calculated as:

The linear speed of the Venus in time can be calculated as:

The angular rotation speed of Venus can be calculated as:

From the values of angular rotation speed of Earth   and Venus , we can say that by applying tangential acceleration through rocket at the surface of the Venus, the planet will not have as same as Earth rotation speed but Venus will be have rotation speed much more closer to Earth's rotation speed.
