2 Page of 6 PHYS-114 Test #1 Summer 2006 [1] (10 pts) A car driving South slows down slightly as it approaches a curve in the road ahead. The car rounds the curve at constant speed and then speeds up slightly as it heads off East. Draw a complete motion diagram for the car as seen by a helicopter hovering overhead. Show graphically how you obtain at least two of your acceleration vectors. [2] (10 pts) The grid below shows two vectors. r r r (a) In the grid provided graphically determine the resultant vector R = A + 2B . (b) Express the resultant vector R in unit vector notation. ! (c) Then determine the magnitude of your resultant vector R and its angle with respect to the positive x-axis. Summer 2006 PHYS-114 Test #1 Page 3 of 6 [3] (10 pts) The velocity-versus-time graph for an object is shown below. Using correct numbers and shapes, draw the position-versus-time graph. Assume that the object is at x = 6m at time t = 0s. [4] (10 pts) For the following problem statement, identify the system and the environment. Sketch a picture of the system and environment. On your sketch, draw and label all of the vector forces acting on the system. You've slammed on the brakes and your car is skidding to a stop while going down a 20 Page hill. 4 of 6 PHYS-114 Test #1 Summer 2006 [5] (55 pts) As a member of the (Kettering Physics Superstars) coed fraternity you are participating in the A-section Greek Games. Your event is the Body Slide in which you dive onto a long, wet plastic slide and see how far you can slide (you also earn points for style). You start running from rest 5.0m 2 from the beginning of the slide and you accelerate at 2.4m/s before diving onto the slide. The slide has a 2 small amount of friction and as you slide you slow down at a rate of 0.6m/s until you finally stop. (a) What is the distance of your slide (on the plastic)? (b) How much time passes from when you start running until you finally stop? MODEL (5 pts): VISUALIZE (35 pts): Summer 2006 PHYS-114 Test #1 Page 5 of 6 SOLVE (10 pts): ASSESS (5 pts): are the speeds, distances and times reasonable? (1m/s = 2.24 mph and 1 m = 1 yard = 3feet) Page 6 of 6 PHYS-114 Test #1 Summer 2006 [6] (10 pts) The plot below shows the position-versus-time graph for an object. (a) Determine the average velocity between times 2s and 13s. (b) Estimate the instantaneous velocity at 9s. 4 pts Extra Credit: Determine the average acceleration between times 6s and 12s.
