Plsss pl plsss Two carts weighing 3kg and 2.5kg move on a smooth horizontal surface with speeds of 2m / s and 3m / s, the directions of which are shown in fig. After the collision the two carts move together as a single body. Find the magnitude of the speed and what is the direction of movement of the two carts after hitting them.​

How would a small bar magnet be oriented when placed at position x?

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
