Three blocks are connected by massless cords and rest on a frictionless horizontal surface. the blocks are pulled to the right. mass m1 = 2 m2 = 3 m3, with m1 on the left and m3 on the right. if the pulling force is equal to 90 n, then the tension in the cord between m1 and m2

Can somebody explain to me how newton's 3rd law relates to momentum? ~ap physics 1

Arrange the images in order to show how lake-effect snow occurs.

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
