Two objects of different mass start from rest and are pulled horizontally with negligible friction by the same magnitude net force and moved through the same distance. The work done on object 1 is 4000 joules. After the force has pulled each object, object 1 is seen to move with half the speed of object 2. Answer the following questions and show your work. a. How much work is done on object 2? b. What is the kinetic energy of object 1 after being pulled? Explain. C. What is the kinetic energy of object 2 after being pulled? Explain. d. What is the ratio of the mass of object 1 to the mass of object 2? Explain and show work.

Calculate the work done by this force.
Problem #1–The below figure shows a 200-kg sleigh being pulled along a ramp at constant velocity. Suppose that the ramp is at an angle of 0 = 30° with respect to the horizontal and the sleigh covers a distance d = 20 m up the incline. The snowy slope is extremely slippery generating a frictionless surface. How much work is done by each force acting on the sleigh?
7. The cart, in the diagram below, travels .80 m down the ramp with uniform acceleration in 1.5 seconds. The initial velocity(v.) is 0 m/s. You must show work. Determine the following. If answer requires a calculation, you must show work. The initial velocity(v.) is 0 m/s. a. Average Velocity b. Acceleration c. The dots in the strips below represent the position of the cart as it rolls down the .80- meter-long ramp. The time intervals between the dots are equal. Which of the strips best represents the motion of the cart down the ramp? Justify your choice. d. Which two strips represent an object moving at constant velocity? Justify your answer.
Identify which case/s below exhibit/s work done on the object. answer in mathematical computations. Describe the work done in the 3 cases. Why does it matter? Case 1: Pushing a 5 kg ball cart from a side of the room, neglecting frictional force, all the way across a 5.0 m basketball court. Case 2: Placing an 8 kg sack of rice on a farmer’s head and bringing it to the nearby dry market, 6 km far from the farm. Case 3: Lifting a 0.65 kg puppy from the floor to the top of a 0.75 high veterinarian’s surgery table.
