For t < 0, an object of mass m experiences no force and moves in the positive x direction with a constant speed v,. Beginning at t = 0, when the object passes position x = 0, it experiences a net resistive force proportional to the square of its speed: Fnet - - mkv? î, where k is a constant. The speed of the object after t = 0 is given by v = v;/(1 + kv,t). (a) Find the position x of the object as a function of time. (b) Find the object's velocity as a function of position.

A crate with a mass of 155 kg, starting from rest, slides down a ramp making an angle of 32 degrees with respect to horizontal. The ramp is 6 meters long. A constant frictional force of 200 N acts throughout the motion and a force Fis being applied by a rope as shown to prevent the block from sliding too fast. Suppose that while traveling at v=0.1 m/s down the ramp, at d=4meters from the end of the ramp, the rope breaks. Use the work- kinetic energy theorem to calculate the speed, in m/s, of the crate when it touches the bottom of the ramp. Use 9 = 9.8 m/s
Answer must be in nanometers.
Mass A is 40 kg and mass B is 10 kg. The angle that the inclined plane makes with the horizontal is 30 degrees. Using conservation of energy, find the velocities of bodies A and B when body A moves 3 meters down the inclined plane, ignoring friction and pulley masses, and when bodies A and B start to move from a standstill.
