A powerful motorcycle can produce an acceleraDon of 3.50 m/s2 while traveling at 90.0 km/h. At that speed, the forces resisDng moDon, including fricDon and air resistance, total 400 N. (Air resistance is analogous to air fricDon. It always opposes the moDon of an object.)
What is the magnitude of the force that motorcycle exerts backward on the ground to produce its acceleraDon if the mass of the motorcycle with rider is 245 kg?

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:
