The coefficient of static friction between a rubber tire and dry pavement is about 0.800. assume that a car’s engine only turns the two rear wheels and that the weight of the car is uniformly distributed over all four wheels. (a) what limit does the coefficient of static friction place on the time required for a car to accelerate from rest to 60 mph (26.8 m/s)? (b) how can friction accelerate a car forward when friction opposes motion?

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:
