1. A rope that makes a 15° angle with th
horizontal pulls a block weighing 3N
distance of 10 meters to the right at a
constant velocity. The tension in the
is a 2 N force. How much work is don
by the rope acting on the block in the
horizontal direction? Let F, be the
tension in the rope and Ax be the
displacement in the x-direction.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
