Earth makes one rotation (2 rad) every 86,400 seconds. The radius of the Earth is 6.371 x 106 meters. Calculate Earth’s angular velocity. What is the expected linear velocity of a person standing at sea level? What keeps us from flying off the surface of the Earth?

The object's initial distance above the groundthe object's initial velocity

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Ok? don't be a fake friend, only be friends with people that you are interested in developing a strong relationship with. don't be fake.
