Sorry if the pic is blurry. Thanks guys for the answer!

Which fators influence ocean currents

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?
