A child applies a force F parallel to the z-axis to a 5.00 kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the z-component of the force she applies varies with the z-coordinate of the sled as shown in figure (Figure 1). Suppose the sled is initially at rest at z =0. You can ignore friction between the sled and the surface of the pond. Part A Use the work-energy theorem to find the speed of the sled at 8.0 m.

A person jumps then leaves the floor with a velocity of 1.20 m/s upward. If the person is in contact with the floor for 0.280 s during the jump, what is the net force exerted by the floor on the person? The mass of the person is 80.0-kg. Your answer
The coefficient of friction between the wheels of Yamaha motorcycle and the dry pavement is 0.88. An animal walks out into the road, causing a motorcyclist to slam on the brakes. The wheels stop turning, but the tires skid along the road, causing intense friction and heat. Determine the magnitude (positive) of the acceleration which the 224-kg motorcycle experiences while skidding to a stop. The mass includes the rider. Answer: m/s/s (or m/s²)

You are working for a shipping company. Your job is to stand at the bottom of an 8.0-m-long ramp that is inclined at an angle of 17 degrees above the horizontal. You grab packages off a conveyor belt and propel them up the ramp. The coefficient of kinetic friction between the packages and the ramp is uk =0.30. a. Your coworker is supposed to grab the packages as they arrive at the top of the ramp, but she misses one and it slides back down. What is its speed when it returns to you?
