Actually, the speed of the earth is the same everywhere, taking the angular speed as the valid measure of the speed
Answer:0.669
Explanation:
Given
mass of clock 93 kg
Initial force required to move it 610 N
After clock sets in motion it requires a force of 514 N to keep moving it with a constant velocity
Initially static friction is acting which is more than kinetic friction
thus 613 force is required to overcome static friction
The answer will be
(1) correct
(2) correct
(3) the force of the soccer ball on the net
(4) Will not change
Hope this help
