Atruck is moving around a circular curve at a uniform velocity of 13 m/s. if the centripetal force on the truck is 3,300 n and the mass of the truck is 1,600 kg, what's the radius of the curve? a. 6.30 m b. 81.94 m c. 109.09 m d. 348.56 m

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.)
