Physics 1408

Since you may take the online quizzes as often as you like, your highest average should be pretty good. However, in order to keep track, you must fill out the student name and id# part of the form.

Question 3. The phase angle for the figure above (in degrees) is

(a) 0     (b) -60     (c) +60     (d) -120     (e) +120

 

 

Question 4. In the figure below, the amplitude of the motion (in cm) is

Question 5. The frequency for the figure above (in Hz) is

(a) 0     (b) 0.25     (c) 0.5     (d) 4.0     (e) 8.0

 

 

Question 6. The phase angle for the figure above (in degrees) is

Question 8. The velocity at t=0 s (in cm/s) for the figure above is

(a) 0     (b) 3.14     (c) 6.80     (d) 7.85     (e) 9.72

 

 

Question 9. The maximum value of the velocity (in cm/s) for the figure above is

(a) 0     (b) 3.14     (c) 6.80     (d) 7.85     (e) 9.72

 

 

Question 10. A 200-g air-track glider is attached to a spring. The glider is pushed in 10 cm and released. A student with a stopwatch finds that 10 oscillations takes 12.0 s. The spring constant (in N/m) is

(a) 0     (b) 3.14     (c) 5.48     (d) 8.15     (e) 11.7

 

 

Question 11. A 500-g block slides along a frictionless surface at a speed of 0.35 m/s. It runs into a horizontal massless spring with spring constant 50 N/m that extends outward from a wall. It compresses the spring, then is pushed back in the opposite direction by the spring, eventually losing contact with the spring. The amount of time (in s) that the block stays in contact with the spring is

(a) .314     (b) .628     (c) .943     (d) 1.26     (e) 1.57

(a) 0     (b) 3.14     (c) 6.28     (d) 9.43     (e) 12.6
