Physics 111 Quiz #6 (Take-Home); Maximum score = 13 points Due October 3, 2017, 9:00 AM Name: _______________________ 1. A crate is being pulled along a smooth surface by two cables. In this top view (looking down), the two arrows represent forces on the crate by the cables. (a) On the grid, draw an arrow representing the net force on the crate; assume there is no friction. Draw only one arrow. (b) Draw an arrow in the empty box representing the direction of acceleration of the crate. 2. The arrows on the grid above are the velocity vectors of an object moving to the right, shown at two different times. (a) Draw one arrow on the grid to represent the change in velocity [vfinal – vinitial] of the object during the time interval. (b) Draw an arrow in the empty box to represent the direction of acceleration of the object. 3. A batter hits a long home run over the centerfield wall; the initial speed of the ball is 44 m/s and it’s hit at a 55˚ angle above the horizontal (x) axis. Ignore air resistance. (Assume positive-y is up and positive-x is toward the wall.) a. What is the x-component of the ball’s initial velocity? Answer: ________________ b. What is the x-component of the ball’s velocity when the ball reaches its maximum height off the ground? Answer: ________________ c. What is the y-component of the ball’s velocity when the ball reaches its maximum height off the ground? Answer: ________________ 4. These questions relate to the ball in #3 above. (Ignore air resistance.) a. While it is in the air, after the hit, what is the x-component of the ball’s acceleration? Answer: ________________ b. While it is in the air, after the hit, what is the y-component of the ball’s acceleration? Answer: ________________ 5. A 1000-kg elevator is rising at constant speed, pulled up by a single cable. (a) What is the magnitude of the net force on the elevator? (b) What is the magnitude of the weight force on the elevator? (c) What is the magnitude of the tension force in the cable? Answer to (a): _____________ Answer to (b): _____________ Answer to (c): _____________
