Quiz 6 1 . It takes a force of 60.0 N to compress the spring of a toy popgun 0.19 m to "load" a 0.10 kg ball. With what speed will the ball leave the gun? __________ m/s 2 . A 1.10 kg box rests on a plank that is inclined at an angle of 75.0° above the horizontal. The upper end of the box is attached to a spring with a force constant of 21.0 N/m, as shown in the figure. If the coefficient of static friction between the box and the plank is 0.20, what is the maximum amount the spring can be stretched and the box remain at rest? __________ m 3 . A spring that has a force constant of 800 N/m is mounted vertically on the ground. A block of mass 1.30 kg is dropped from rest from height of 1.10 m above the free end of the spring. By what distance does the spring compress? __________ m 4 . A 26.0-kg block is resting on a flat horizontal table. On top of this block is resting a 17.0-kg block, to which a horizontal spring is attached, as the drawing illustrates. The spring constant of the spring is 335 N/m. The coefficient of kinetic friction between the lower block and the table is 0.490, and the coefficient of static friction between the

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
