2.00 kg, and the pulleys are frictionless. (a) draw a free- body diagram of each object. (b) determine the accel- eration of each object, including its direction. (c) deter- mine the tensions in the two cords. what if? (d) if the tabletop were smooth, would the tensions increase, decrease, or remain the same? explain.
under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. when the drive force is shut off, the snowmobile coasts to a halt. the snowmobile and its rider have a mass of 136 kg. under the influence of a drive force of 205 n, it is moving at a constant velocity whose magnitude is 5.50 m/s. the drive force is then shut off. find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so.
