Calculate the gravitational force on the washers using the formula f = ma where a = 10 m/s2 and m is the mass of the washers. use the mass of the washers in kilograms. record your calculations, to no more than three decimal places, in table d. note that the force of gravity on the washers is the same as the applied force of the washers on the car. the force applied to the car by one washer is kg · m/s2. the force applied to the car by two washers is kg · m/s2. the force applied to the car by three washers is kg · m/s2. the force applied to the car by four washers is kg · m/s2.

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:

Select for each of the following statements whether it is correct or incorrect. (a) in an isothermal expansion of an ideal gas. (b) the temperature remains constant. (b) the pressure remains constant. (c) there is work done by the gas. (d) there is heat added to the gas. (e) the change in internal energy equals zero.

Suppose that 27 j of work is needed to stretch a spring from its natural length of 6 m to a length of 9 m. (a) how much work is needed to stretch the spring from 12 m to 14 m? j (b) how far beyond its natural length will a force of 78 n keep the spring stretched?
