Chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck and his cart, image for chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck, is identical to the combined mass of jackie and hercart. initially, chuck and jackie and their carts are at rest.

chuck then picks up a ball of mass m_ball and throws it to jackie, who catches it. assume that theball travels in a straight line parallel to the ground (ignore theeffect of gravity). after chuck throws the ball, his speed relativeto the ground is v_c. the speed of the thrown ball relative to the ground isv_b.

jackie catches the ball when it reaches her, and she and hercart begin to move. jackie's speed relative to the ground after shecatches the ball is v_j.

when answering the questions in this problem, keep the followingin mind:

the original mass image for chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck of chuck and his cart does not include the mass of theball.
the speed of an object is the magnitude of its velocity. anobject's speed will always be a nonnegative quantity.
part a
find the relative speed u between chuck and the ball after chuck has thrown theball.
express the speed in terms ofv_c and v_b.
part b
what is the speed v_b of the ball (relative to the ground) while it is in theair?
express your answer in terms ofm_ball, image for chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck, and u.
part c
what is chuck's speed v_c (relative to the ground) after he throws theball?
express your answer in terms ofm_ball, image for chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck, and u.
part d
find jackie's speed v_j (relative to the ground) after she catches theball, in terms of v_b.
express v_j in terms of m_ball, image for chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck, and v_b.
part e
find jackie's speed v_j (relative to the ground) after she catches theball, in terms of u.
express v_j in terms of m_ball, image for chuck and jackie stand on separate carts, both of which canslide without friction. the combined mass of chuck, and u.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
