Hans Full is pulling on a rope to drag his backpack to school across the ice. He pulls upwards and rightwards with a force of 22.9 Newtons at an angle of 35 degrees above the horizontal to drag his backpack a horizontal distance of 129 meters to the right. Determine the work (in Joules) done upon the backpack. 3. A bicycle has a kinetic energy of 250 kJ. What kinetic energy would the bicycle have if it had twice the mass and was moving at the same speed? 4. A bicycle has a kinetic energy of 250 kJ. What kinetic energy would the bicycle have if it had the same mass and was moving with twice the speed? 5. A 50 kg log is floating above a waterfalls at a rate of 10 m/s, What will be the resulting kinetic energy in lbf-ft if the log falls down the waterfalls with a velocity of 30 m/s? 6. Water from a hose is being discharged straight vertically upwards until a height of 32 ft. What is velocity of the water from the hose in m/s? 7. A force of 50 lbf is being applied to a box causing it to move at a rate of 20m/s. Find the power in Btu/min.
