Suppose a solution is prepared where x2=0.050. assume the solution is regular, use the exchange parameter w calculated in part d to determine the freezing point lowering δt. assume δh¯fusion=6010j/mol . assume w is constant over the range δt.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

Auniform crate c with mass mc is being transported to the left by a forklift with a constant speed v1. what is the magnitude of the angular momentum of the crate about point a, that is, the point of contact between the front tire of the forklift and the ground
