Asmall block of mass m1 is released from rest at the top of a curve-shaped, frictionless wedge which sits on a frictionless horizontal surface. the height of the wedge is h=5m. when the block leaves the wedge its velocity relative to the ground is measured to be 4 m/s to the right. if the mass of the block is doubled to become 2m1 what, what will its speed be when it leaves the wedge?

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
