Practice with workcontext You want to practice using the notions of work and energy in physics situations. You imagine a block pulled on a horizontal surface (along an x-axis), without friction, for which you are looking for the final velocity. Known information: the mass of the block;the tension in the rope;the initial speed of the block;move. Schematization Draw a diagram of the object that interests us. Draw your x and y axes. Draw and name each force experienced by the object of interest and identify its displacement. Modelization Design a model to calculate the modulus of the block's final velocity as a function of known parameters, using the notions of work and energy. Then test your model with the following values: Block mass: 7 kg Initial Velocity: vi = (3.6 i ) m/s Displacement: s = (4.4 i) m Tension in the string: T = (17.2 i ) N

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.

Three objects with masses m, = 4.8 kg, m, = 14 kg, and m, = 17 kg, respectively, are attached by strings over frictionless pulleys as indicated in the figure below. The horizontal surface exerts a force of friction of 30 N on m,. If the system is released from rest, use energy concepts to find the speed of ma after it moves down 4.0 m. 5.1 Your response differs from the correct answer by more than 10%. Double check your calculations. m/s
Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes accelerate 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car. If the gas station is 200 meters away and the friction force against him is exactly equal to the force applied in part a, how much work did Mike do?
