A mass of 2 Kg is attached to a spring on a horizontal frictionless surface. It is observed that the spring exerts a (81/50) N force when stretched by (1/100) metres. Apart from the spring force and the damping force there no other external forces on the mass. In two separate experiments A and B it is attached to two different viscous dampers. A) A viscous damper that exerts a damping force of (27/100) N when the mass is moving at (1/100) ms^{-1}. B) A viscous damper that exerts a damping force of (9/20) N when the mass is moving at (1/100) ms^{-1}.

An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

Several mountains together form a mountain . a few of these combined form a mountain system. several systems combined form a mountain , which can stretch thousands of miles in length.
